Secondly, if you want to run smoothly, you need to have a powerful CPU. 1000W wants to be smooth, the minimum must be 4 cores. Neither the rendering nor the modeling stage has anything to do with the graphics card, which is only responsible for fixed operations (such as mapping, texturing, etc.) and not on-the-fly operations.
Additionally, don't fetishize professional cards, they are just more suitable for graphics, the most direct manifestation of which is that the user's view in MAX with good lighting and textures and the final image after rendering have a very small gap. Does not mean that it can handle a lot of polygons, rendering will not be fast to where. What's really fast is a graphics workstation, but it's expensive, tens of thousands or hundreds of thousands of dollars.
So your focus should be on the CPU and memory, not the graphics card, they say the A card is very suitable for graphics, but I use the N card to do it is also quite cool. the A card driver and so on is very troublesome, it is recommended to go on the N card, and say you use the intel U, with the N card is good, go on the AMD U with the A card is better.
