Hey, i was just curious about the difference in playing UT2K4 on an iBook G4, 32 vram, 256 RAM compared to playing it on an iMac G5 128 vram, 1 gig RAM. Now im sure the iMac is better than the iBook. The loading times on my iBook were like 3-5 min. playing UT2K4. How about on an iMac G5? How good is the iMac G5 with games like Doom 3, UT2K4, Call of Duty, etc.
