My recommendation is to get the 2GB video card, but also wait until late Oct. I'm opting to "roll the dice" and hope that Apple comes out with an Ivy Bridge processor with faster RAM, USB 3.0 and maybe a better screen (probably not retinal display?) sometime in October as so many swarming rumors have suggested. I understand it's speculation but I decided to wait another month - just in case. I'm sure they're going to implement the new processor in the iMac at some time in the near future!
