i dont see what the big difference is, Im thinking about making the leap to Mac from a PC, (i have some background of macs cause my cousin is a extreme left wing MAC man) and i love the screens on the new imacs... I do play the occasional Game like WoW and this game called wolf team, but i want something that will be able to handle Diablo 3/ star wars the old republic. whats the difference between the different video cards at both 256 DDR3... do you guys think the 2 base models of the imac can handle it? I want to make the leap so bad but i cant afford the more expensive Imacs. for over 1,000 i really hope they can handle it... cause you can get a pretty badass PC set up for less then a grand (please dont flame im still learning!) PS: i LOVE mac os!
