Hi all, new to MR. I've set my mind on a 24" iMac. I don't care about possible new releases... So with that in mind I want to play COD4 and StarCraft II when it comes out. I'm thinking to max it out with 3.06ghz, 4GB ram... do I get the GeForce too? I've read forums here on the 8800 and some people had issues with it back in May... has that been fixed? Should I stick with 2600? Money isn't the main issue, quality of the game experience is. Thanks!
