Give a configuration for your reference. This is my own configuration, but it's actually just a suggestion under my blueprint.
CPU:E5200 (5 capacitors, not boxed, only in bulk) 420 If you must have E5300, be sure to ask if you support VT technology.
Fan: Overclocking 3 Red Sea 60
Motherboard: Zappo X-BLUE P43 380
Memory: KINGMAX DDR2 800 (the previous price is not suitable now). The memory is not oily, and the price is similar to that of online newspaper. I'll calculate it as 140.
Graphics card: Onda 9600GSO 384M 475
Hard disk: Seagate 12 generation single disk 500G (I didn't use Seagate, mine was 640KS 4 15), estimated at 360 degrees.
Speaker: rambler R 10 1T06 (recommended, with good reputation). I remember the reserve price seems to be 130 degrees.
Power supply: Hangjia Cold Drill 2.3 185
Chassis: 100 (optional)
Monitor: LG 1942SP I heard that it is now 799, but it is estimated that it can be cut by dozens of degrees.
If LZ matches the machine at my price, it will basically not be cheated, because I have cut it perfectly. It is estimated that those js are not willing to trade at this price. LZ should be careful not to be replaced.
This is a cost-effective configuration that absolutely meets all your requirements. Running 3DMARK06 can pass 10300, and overclocking is better. 420+60+380+140+475+360+185+100+799 = 3049. Are you satisfied ~ ~
Look at the price on the monitor, which is similar to your budget. I have made great efforts to help LZ, and I really have nothing to say if I am not satisfied. Adopt me ~
