I don't game as nearly as much as I use to but since I plan to keep an iMac around for a while this means I will probably put Windows 8 on it when it comes out. I MIGHT get the 2012 iMac when it comes out, depending on how much it changes. But for now, lets just assume I'm getting the baseline 27" model iMac. Based off that assumption how good is it for gaming? Also, note like I said I don't game very much at all, so I'm not expecting to run Battlefield 3 at ultra settings here.
