Hi, I am going to buy a 2.8ghz 24" Alu iMac in the new year, a question I have is is the ATI Radeon HD 2600 PRO graphics processor 256MB of GDDR3 memory good enough to run Windows games such as Gears of War, UT3 and the like? Also, have there been any rumors of an updated iMac (the new intel chips, new graphics card, etc.) being released in the new year after Macworld as I want to make sure that I get the most "up-to-date" mac I can? I am being careful this time since I bought my old iMac a couple of years ago and then the intel based macs were released 2 weeks later, I was gutted since I didn't research / read any news, not this time! Thanks helping this newbie.
