It depends on how large the model you want to run.
If the building owner is mainly used for learning, in fact, these software building simple models do not have high requirements for GPU, but have simple requirements for CPU. The building owner's CPU can be positioned at the low end, but not too bad. It is recommended that at least G3420 products be used. If you just build a very simple model, the core and display can run smoothly, but with the increase of the model, the requirements for the graphics card will become higher and higher. Building is mainly based on its own model size graphics card.
As for what the graphics card thinks of this kind of thing, in fact, most of the parameters are of little reference significance to those who just come into contact with GPU. Because the architectures of nvidia and AMD are different, and even the number of SPs of the products of the two brands with different architectures cannot roughly correspond to the performance, it is recommended that the owner not simply look at the parameters of the video card. The building owner can understand the general positioning of the graphics card through the evaluation, but because of the optimization of the adobe product for the N card, it is generally recommended that if you use the adobe software, you should try to use the n card. It is recommended that the building owner try the GTX750ti level graphics card first. If you can borrow it, try not to buy it first (because most CPUs on the Intel LGA1150 platform currently have a core display, and the graphics card still needs to be used). It is not too late to spend money when you feel that the test is suitable for you.
