Building a computer for my brother (Industrial Design student) who will be using it for gaming and CAD work (3-D work, not easy 2-D drawings) and wondering if the GPU matters what I go with. The three/four I'm looking at are the 6950, 6970, GTX 570, and GTX 560 Ti.
What I'm wondering is which card will perform better in a CAD environment. I know the nVidia cards have CUDA cores on them but I don't know how well they actually perform compared to the AMD cards. I'm not worried about the gaming performance of these cards, I know they will all be suitable for his needs, but the CAD stuff is where I'm lost.
Does it matter which one I get, or will they mostly all perform about the same in comparison to each other?
How big of a difference will there be between a CAD (FirePro / Quadro) card and the cards I listed in CAD work?
An example of his work - he's not doing assemblies or anything like that as far as I know so it doesn't have to be a card that would render a fully-functioning 787
