Much as I like the design of the G5 iMac I've always been out off by the reportedly lacklustre graphics performance. Can anyone confirm that the new 20" G5 iMac (with built in iSight) is good enough for the occasional game of BF 1942, Rainbow 6, etc? As a reference point I have a 15" PB (1.25 GHz, 1 GB RAM, 64 MB Radeon Mobility 9600). Will the Radeon X600 be much faster, despite driving a higher resolution screen or will I have to run it at a (non-native) lower resolution to see an increase in frame rates? Will I still have to tone down effects, etc? (The reason I am so suspicious is that a tomshardware.com test of various graphics cards put the X600 fairly low on the list of current cards. Other cards were 4-5 times faster) I'm guessing the G5 processor will make a difference too - BF 1942 seems to slow down depending on how many people are playing at once. Mostly the machine will be used for FCP, iLife and DTP. Dual cores would be nice but I like the portability of the iMac. Hoping for some feedback. Thanks!
