OK folks I need some input on the video cards that Apple offers with their G5 systems. 1) Is the ATI 9600 worth the extra $45? I have an ATI card now and never had proplems with it. 2) When I got my current video card I was disappointed that the screen "redraws" from my CAD program did not improve. I was told that this had more to do with the CPU and not the graphics card. My question is: At what point does the CPU pass control to the GPU on the graphics card? What part of rendering is done by the CPU and how much of the processing does the grapics card do?
