Before we buy, we need to draw up our own configuration
The purpose of drawing up this configuration is not to let us pick what kind of cost-effective accessories, but to let us figure out what the main purpose of buying a computer is. The first thing we need to consider is the amount of money we have on hand and how much we have budgeted to invest in the computer. After making a budget, we will consider the purpose of the computer we buy, usually we will use it to do what things, as much as possible to think of a more comprehensive point.
For example, if the application in the entertainment, we hope that he achieved a what effect; if we apply to the drawing, then we need what kind of display effect, what kind of picture processing speed, with this idea we then consider what kind of monitor to buy and graphics card; in the case of limited funds we should have a focus on the purchase of computers, take the author: the main purpose of the computer is to write articles, surf the Internet. The main purpose of the computer is to write articles, surf the Internet, and listen to music, then the focus of the computer is naturally placed on the performance of the stability of the monitor, sound card and speakers and every day to use the input device keyboard and mouse. That is to say, according to our main purpose to configure their own computer. General student users, with the focus of the machine for: cost-effective, speed, stability; home users focus on: computer comfort, stability, speed, price. With the goal, how do we choose what we need from the wide variety of accessories? Let's take a look at some of the articles on saving options, see what different accessories are used for, get some basic knowledge, and then read some of the reviews.
If you're considering a future upgrade, you can refer to some of the website's reviews of various processors and the comprehensive long-term planning of the relevant official websites to understand some of the knowledge, we can know how long the application cycle of the accessories we buy is, and whether to support the upgrade of the new version of the accessories in the future. Usually when we configure a computer first choose the processor, such as whether to choose Celeron or athlon xp, the computer is concerned about the overall coordination, how to rationalize these accessories and accessories to play the performance is the key. Choose a good processor and then choose the motherboard, a good motherboard is the core of the whole computer, which determines the speed, stability, compatibility and future upgrades we seek. Then go to the selected hard disk and memory, to build a basic platform we have to consider the whole computer is outstanding speed, or stability, or excellent cost-effective, for other accessories to buy a good framework. On the basis of this platform we can according to the different focus of each person in the choice of other accessories. At present, many of the computer's mid-range and high-grade accessories will be a small increase with the funds and cost-effective substantial increase in the price is very tempting to buy the heart is very contradictory, the pursuit of cost-effective tend to exceed the budget, and then buy back the accessories in their own platform may not be able to play out the proper performance, it is very difficult to choose whether to pursue more cost-effective or to see a good deal, I advocate enough to be good. In our enough machine before considering the use of the machine than to understand the performance of the accessories more meaningful, consider a good use and focus we will begin to consider the purchase of accessories.
Some of the problems that should be noted when purchasing machines
After making the configuration, you can find some masters to give some advice, mainly to see whether the configuration is reasonable, there is no compatibility problems, etc., and then the end of the paper, go to the market to see. Go to the market to visit some of the field, and different merchants to communicate, and refer to the merchant's certain opinions, pay attention to their objective review of a product, what are the advantages what are the disadvantages. After all, not every businessman is js, because they are all day in the market crawling and rolling, familiar with the advantages and disadvantages of a product and the return rate. And we generally see some of the articles are not very impartial, in order to make the right investment, find a master together to the market to see is very necessary.
The only thing we have to pay attention to in the purchase is not to buy fake products, now many mainstream accessories will be published in the media, some pictures of accessories and counterfeiting notices, we may wish to pay attention to, and many of the accessories have opened a 800 toll-free lookup phone number, accordingly, some of the computer towns and merchants have made a commitment to some of the counterfeiting, where it will be better to buy.
In addition to the fake is the water goods, water goods than the regular channels of the real thing to be cheaper than a few dozen dollars, the two in the performance of no difference, but in the warranty on the big difference, so in the purchase of hard disk this kind of accessory first understand the hard disk warranty label. In the purchase of the machine, pay attention to the accessories of the package whether there are traces of the two packages, whether they have been used, do not just look at the chassis when you buy its appearance, focus on the chassis of workmanship, whether it is conducive to heat dissipation, because the chassis of the heat dissipation is also the key to the stability of the system. Although it is now rarely used floppy drive, but we must be more careful when buying, because the most fake is the floppy drive, the price of the real floppy drive is almost the same, even if it is not commonly used, buy a real or better. After purchasing, ask for a specific warranty and receipt from the merchant, as this is the proof of warranty in the future.
Not to be overlooked some of the accessories
A good performance of the computer, if not the power supply or power supply problems in his performance and how to play out? At present, high-speed hard disk, high-grade graphics cards and a variety of radiators have stepped into the computer chassis, there is no doubt that the performance of the power supply has a new test, a good power supply can not only filter unstable input current, but also for the machine to output a stable current, greatly reducing the phenomenon of inexplicable restart of the machine, so we should pay attention to the purchase of the computer's power supply, try to buy a number of well-known power supply, according to the different configurations, the power of the power supply is also a different choice. The power of the power supply is also different, if in order to better let your "baby dragon" to play out the outstanding performance of a good 300w power supply is essential. At the same time, we should note that some brands of power supplies and the purchase of the motherboard will have certain compatibility issues, then we have to choose to replace the power supply rather than replace the motherboard, because this is the excuse for some js, he will try to change your mind to achieve their own purposes.
A good radiator is also a non-negligible accessory, now the processor heat, how to make the processor work in a good state and not work under the noise which is determined by a good fan, perhaps many consumers will be the same as I initially have the same idea, spend tens of dollars or even hundreds of dollars to buy a fan is worth it? I finally understand after a month of fan pain after the upgrade to buy a good fan is very worthwhile, there is a good fan to accompany the cpu machine will work very smoothly, not often when you do the finishing work crash, at the same time smaller sound will not affect your work, of course, not every processor needs expensive fan, if you choose the processor is better, it is still believe that old saying: A good horse needs a golden saddle!
Additionally, the average home user should focus on the mouse as well, because the mouse is the most basic input device, for home users, the mouse is used more often than the keyboard, even if you do not go online to buy a 3d mouse is also very necessary, you can operate the computer faster, and also improve the efficiency of the computer.
In short, the purchase of computers is not very complex, as long as the usual more look at some accessories related information, more computer knowledge on the purchase of computers is very helpful. I wish you to buy your first computer!
================================================================================================== A few examples of unreasonable computer allocation:
Accessory disability type
We are not talking about a physical disability here, let alone a faulty computer accessory. But we certainly understand that a brave cheetah limbs, but prefer to grow chicken claws will be how? It can only be described as a physical disability. In real life this kind of thing is not common, but in our saving program will appear a lot.
A certain college student aimed at today's rapidly evolving software needs in his computer, and recognized the word "big". Let's take a look at his program:
CPU: P4 2.6G
Hard disk: 40G
Memory: 256M
Graphics: GEFORCE MX200
Chassis: a brand of high-grade deluxe chassis
Sound card: on-board
Speakers: Audiophile active speakers
......
But from these few accessories above, it seems as if this computer is a very good configuration. The problem is that the hard drive is a 5400 rpm hard drive. The computer's performance requirements are very high, and the students claimed to be obsessed with 3D games. But in reality, the computer's configuration is full of problems, and the actual application may not be able to achieve the desired results.
First of all, we should understand a common sense of hardware when saving a computer: similar to a good horse with a good saddle, high-performance computer accessories also need other high-performance components to play a perfect effect. This is the first time I've ever seen a computer with a P4 1.7G, and I've never seen a P4 1.7G with a P4 1.7G, and I've never seen a P4 1.7G with a P4 1.7G. But this student somehow graphics card is only selected MX200, if it is for budgetary considerations does not make sense, the chassis are equipped with such a high-grade, you can choose the general chassis, save money to subsidize the graphics card. Wouldn't a GEFORCE MX400 or higher graphics card be better for 3D gaming?
In addition, the configuration of the choice of 5400 rpm 40G hard disk, if from the point of view of the pursuit of speed, is not quite appropriate. This is because the platform choice for the whole machine is very high-end and high performance. But in the hard disk but chose a relatively low performance 5400 rpm hard disk, will have a significant impact on the whole computer performance balance. Like a cheetah with chicken claws, what's not a disability? Not to mention the choice of high-level active speakers only with a poor on-board sound card to drive the words, it is too big to use. At this point, even if the speakers are good, but also can not send the sound of heaven. A more appropriate example is the barrel effect, in which the performance of the entire computer system will be determined by the low performance of any one component. A high speed CPU with a good chipset paired with a relatively low performance hard drive will result in a low performance disk subsystem, which will directly affect the entire system. The display subsystem is also paired with the MX200, how can 3D performance be improved? Audiophile speakers will not do any optimization of the sound quality of the flat on-board sound card issued by the sound, but will make the shortcomings revealed. "Ask where the channel is clear, for there is a source of living water." This saying couldn't be more relevant here.
Recommended Changes to Configuration:
CPU: P4 2.6G High-End Type)
Hard Disk: 80G 7200RPM
Memory: 256M
Graphics: GEFORCE TI7500
Chassis: Ordinary Chassis
Soundcard: Onboard
Speakers: Ordinary Active Speakers

Dysfunctional
Just entered the unit of Li is mainly responsible for graphic design, the unit allows Li to report their own allocation of a purchase order. Xiao Li opened the following configuration:
CPU: P4 1.4GHz kit
Hard disk: IBM Tenglong III 60G
Motherboard: kit D850GB motherboard
Graphics card: XXX brand NVIDIA graphics card
Sound card: a 6-channel sound card speaker kit
Memory: kit 128MB Rambus
Burner: XXXX brand
Optical drive: XXX brand 48X
Monitor: 14-inch LCD
A closer look at this graphics-oriented setup reveals a number of problems. First, the choice of an NVIDIA graphics card was not a good one. I don't mean to denigrate NVIDIA, but in the case of many graphics users, it's an indisputable fact that we're all going to be choosing graphics cards with high display quality, such as ATI, and NVIDIA's graphics cards are leading the way in the gaming world, so if you're a graphics user, you're going to want to go with ATI. The first thing you need to do is to get your hands on an ATI card, and you'll be able to do it on your own, with the help of an ATI card, which can be used in a variety of ways.
Revisiting the 6-channel sound card and speakers, we also found a burner and 48X optical drive in the whole configuration. As we all know, a 6-channel sound card must have a signal source in order to function as a 6-channel sound card. And in this configuration, no DVD ROM is seen to appear. And as we all know, CDROM as the carrier of audio and video sources rarely have 6-channel signal. So the 6-channel speakers and sound card here have become a waste of time, and tasteless chicken ribs?
The most dysfunctional accessory in this configuration is the 14-inch LCD monitor, and it's true that LCD monitors have made a big splash in the past year. But not just any application is a good fit for an LCD. In graphic design, the need for large format, the need for high-quality color display. Both of these are drawbacks of current LCD monitors. Perhaps the only reason for choosing an LCD here is the low geometric distortion. But in order to do so, it also brings the most terrible two disadvantages, which are not worth the cost.
Second, the configuration has only 128M of RAM, which is not enough to handle graphics. At the same time, the hard disk also chose a general IDE hard disk, recommended to choose SCSI, or with a RAID system, in order to improve the performance of the disk subsystem. These issues are very important aspects of graphics processing.
In summary, this configuration, if applied to graphics processing, will have a direct impact on the efficiency and results of the work, and it is not too much to call it dysfunctional.
Recommended changes to the configuration: (high-end applications)
CPU: P4 1.4GHz kit
Hard disk: SCSI hard disk
Motherboard: kit D850GB motherboard
Graphics card: ATI RADEON 8500
Sound card: on-board or ordinary sound card
RAM: 256 MB Rambus (motherboard support can be larger)
Writer: XXXX brand
Optical drive: XXX brand 48X
Monitor: 17-inch Triton monitor (EIZO would be better)
Embroidered pillows type
A gentleman recently could not resist the temptation of the overwhelming computer advertisements, can not resist falling behind the The information age is in full swing. To save a computer to catch up with the fashion, decorate the home of the knowledge of no gas. Every day, I see advertisements saying that the computer market is a place of pure flatness, and I remember this truth when I went to the computer market. In front of a computer counter, Mr. A specified that he wanted a BenQ flat screen. The dealer looked happy, said the company just launched a Ben 4 flat special models. The configuration is as follows:
P4 1.4G 423-pin
17-inch flat panel display
Miscellaneous P4X266 motherboard
128M SDRAM
TNT2 graphics
40G 5400RPM hard drive
Premium-grade subwoofer active speaker
This is the first time that I've seen a P4X266 motherboard. ......
A gentleman took a look, not bad, the price is fair, such a low price can be installed to the Pentium four pure flat! Dealers also deliberately P4 INSIDE LOGO glued to the most conspicuous position on the chassis. A gentleman looked more like, yes, and the same as in the advertisement, said also humming the background music of the P4 advertisement ...... happily back home.
Such a configuration is really an embroidered pillow, the surface is beautiful, the belly of the straw bag. Similar configurations in the brand-name machine manufacturers to fight the price of the station time and again, now compatible machine also learned. A few accessories high-end high-grade, but the rest of the accessories are indeed relatively low-grade products. In terms of this configuration, the miscellaneous P4X266 motherboard, 128M SDRAM memory how to play the effectiveness of the P4? More puzzling is the choice of TNT2 graphics card, the dealer to do so in addition to the cost of the reason, is there any other considerations? Needless to say, the 423-pin P4 is at the end of its tether, not to mention the pseudo-flat panel display that employs the usual picture tubes. The whole computer is called an embroidered pillow is true to its name. Of course, this configuration program also has the characteristics of the cheap, which is no excuse. But consumers to face the problem of the mentality to buy such embroidered pillows of the computer can be said to be irrational consumption. For the same amount of money, choose a balanced performance, accessories pragmatic PIII or ATHLONG will bring more powerful performance.
The same example is also true of many consumers who pursue a one-step process, but their own applications can't keep up, directly resulting in a waste of performance. The computer is bought to use, not face, and should not only serve as an embroidered pillow.
Recommended changes to the configuration: (mainstream)
CPU: AMD ATHLONG XP 1.6G
17-inch flat screen monitor
Name brand KT266A motherboard
256M DDR
MX400 graphics
40G 7200RPM hard disk
This is the first time that a computer has been used in a computer system. p>......
Cost-performance disorder type
The pursuit of cost-effective is the purpose of the vast majority of the save, but often in the pursuit of cost-effective at the same time but into another misunderstanding. The most important thing is that most of the students in school will have such an intention, and this student of mine is no exception. The company's main goal is to provide the best possible service to its customers," he said. "I don't like playing games, so I don't have a high demand for 3D performance, and I'm on a budget, so I'm just looking for a bad video card. This can be done with the least amount of money to install a computer. If we put aside other products, maybe this student's point of view is correct. But when we have a better choice, this program may not be the best.
As we all know, before the 815EP motherboard came out, INTEL had already released the 815E chipset with an integrated graphics chip. And the 815E integrated graphics chip 3D performance can be comparable to TNT2 series graphics cards. What's more, the price of the integrated 815E motherboard is the same or even lower than that of the 815EP. It seems that the students if you choose the 815E motherboard can save a TNT2 graphics card funds, the pursuit of cost-effective is to spend every penny to the knife edge. If you choose the 815EP not only does not save money, but also does not bring performance improvement, then why bother? According to this example, the purpose is to tell you not to go into the wrong price-performance ratio disorder, there are many similar examples. For example, the motherboard itself already has an on-board sound card, there is no need to buy a cheap external sound card, the performance is similar, why spend more money?
Recommended changes to the configuration: (economy)
Celeron II900
815E motherboard
40G 5400RPM hard disk
50X CDROM
128M SDRAM
17-inch normal flat
When the system is not in use, it is not necessary for the system to be in use.
