In case you don't already know, (Highly unlikely ), there's a new 24" iMac out. The advantages of this one over the £400 less, 20" iMac model is the 4 inches of extra screen and the nVidia 7300GT card. Is it worth it to go the extra 4 inches, purely for gaming purposes? Is the new card that much better? I'd like to point out that on either model, I'd get the 256MB graphical RAM.
