I'm looking at the iMac -- and have been forced to wait another week to get it. I want to get it with a 24" screen -- but don't know what Proc to get. I know the 2.8Ghz would be a nice addition -- but is it really worth it? I don't play that many games -- and when I do -- it's nothing like Crysis. I'd occaisionally play Counterstrike Source or Halflife. I may do some MILD photo editing... If I could spare the $250, it's be great. I already have ram sitting here for it... I'd use the cash to get a decent external HD for time capsule and a 500 gigger in the PC itself. Any thoughts? Want to convince me that the 400mhz is worth it.
