Those descriptions aren't very telling at all. Questions, Questions. - Whats the budget? - Are you rendering on that machine? - Hopefully that's DDR3 and not DDR. And those 2 processors aren't really comparable IMHO. I'm not loving that ATI video card: Check the Maya compatibility list. And it kinda irks me when these cards are marketed with the "1GB" buzz word to take attention away from the bit rate, 256MB min I say.
