Many consumer level video cards are not officially supported by maya but may still work perfectly. I got GForce 6800GT 256MB and I'm totally happy with it. Haven't encountered any problems even with hardware rendering.Originally posted by gster123
The Gforce isnt supported by maya so theres no gurantee its going to render particles etc.
I'm not sure on the ATI but there is a similar card installed on a machine at uni that appears to run Maya quite well with no probs but i'm not sure if its fully supported (check out alias's site for info on qualifying cards)
I do know that the Quatro range of cards are fully supported so go for one of these if poss as its a profesional graphics card and not a high end gaming one
