I would like to know what do you think of the iMac 24" as far as gaming is concerned. Is it a decent gaming machine? I am thinking of having a separate partition with XP inside it, just for gaming. I would like to play games such as F.E.A.R. and Half Life 2. Is this machine enough? I will buy it with the built-to-order upgrade nVidia 7600 GT. Is it a good card?
