Hey, guys and gals, I'm looking to decide the difference in gaming performance between the 3.06GHz iMac and the entry-level Quad-core Mac Pro. I've found a plethora of online figures showing framerrates of modern game benchmarking running native under OS X. But, I haven't found anything regarding the Mac Pro games to speak of, especially with the upgrade GeForce 8800 GT card. Does anyone own this Mac Pro and can attest to its performance on modern games? This will play a part in my decision making process.
