Im wondering what GPU would be best for -3D modeling- Rendering Speed-graphics
Im not a hardcore gamer but a graphic artist looking for a GPU working with the Quad Core Q6600

In research it seems ATI has more Streaming Processors than Nividia >even though i liked Nividia more at first-

Any ideas of what GPU components are best for intensive graphic rendering?

CPUs

GPU is used in some apps; so it really depends on what apps you are running as to whether you will benefit from a GPU at all.

I want the student version of Maya--And if the price is ever justified Auto CAD or Solid Edge

You are going to have to do some research my friend to figure that out. Really graphically intensive apps that aren't gaming related generally require workstation cards. The good ones are not cheap either...
