Hi there! I'm going to purchase an iMac for my younger brother. But since I've spent a lot of money for my own custom-spec'd iMac, I can only handle the baseline one. Since my brother will play some games like d3, sc2 and lol, there's some need in the information about the specs of 640m that is currently in the iMac (clocks, bus width etc.), not the theoretical one. So please, could some of you guys run a GPU-Z under the bootcamp and post the screenshot of it here? Would really appreciate that.
