My mistake...that's good news though, I wish mental ray could use my GTX580!
For view port viewing in Max and gaming what would you suggest with a budget of 400$? search for my posts if you need more detail I have asked the question there as well
You could get a GTX570 for those $$. However I have not seen one advertised with more than 1280 mb VRAM...

actually quadros aren't fast...
they are stabler and will really give you rendered result as you would get from CPU rendering. but they are not fast as gaming one. buy geforce with many Cudas(I guess GPU vray uses them, at least iRay does use..)
