But aren't they in bed with ATI these days?
The MacBooks and Mac Minis use Nvidia, as well as the iMac's base integrated option. The upgraded iMacs use ATI. The Mac Pros use a Geforce GT 120 as the base with an optional Radeon HD 4870, so it's pretty much all over the place.
I do know that they were pissed at nvidia for a while with a lot of faulty graphics cards in the MacBook Pro line. I just don't know how ATI's low power integrated chips compare to Nvidia's.
