GTX 280 and Maya Support
Can the GTX 280 or any other standard desktop GPU accelerate Maya rendering or must someone get a Quodro Workstation card to do such things?

Im helping my friend build a rig for Maya rendering.

Re: GTX 280 and Maya Support
Rendering isnt helped by GPUs at all.
Mental ray has some OpenGL assist on shadows though I think, but I suspect the difference is very minimal.
Unless youre refering to viewport rendering, Geforce GPUs seems to do well enough there.
Its a bit unmotivated to shell out the money for a Quadro really.

for rendering performance, a nice quad, I think I saw the Core i7 performing ALOT better in rendering then C2Q CPUs.
And sufficient RAM, 4Gb should be plenty for most type of scenes, thats sort of up to what kind of scenes you work with.
Pretty easy to gauge though, just fire up a scene and watch memory usage I guess. add RAM as needed.

Rendering benchmarks on Core i7

weather the GTX series have any viewport issues might be good to know forhand though.
On XP, I had some really wierd viewport Issues in Maya with my 8800GT.
Not on Vista though.
The 8800 series also have severe performance issues in Multidisplay modes on XP in MotionBuilder, work around that by using Span Mode... Dual View works on Vista though.
If the GTX series has any similar issues, maybe someone who has one can provide some input on that.

So would you recommend ATI then?

I dont know how well they work, what issues there may be, if any.
Can only speak of my experience with my current 8800GT.

Which works fine now, with Vista, and knowing some workaround for some issues.
For example selecting highpoly objects was very slow until I found adding this line to the Maya.env file.
set environment variable MAYA_NO_VERTEX_ARRAY_SELECT = 1

Apparantly a 8800 specific issue.

Btw Im hearing the GTX 280 can be somewhat loud.
If Maya causes the fan to spin up, it could be an annoyance to work with that noise.
Gaming you often use headphones, or atleast have alot of sound from the game, so its prolly less of an issue there.
