Quite evidently, Mac computers have never been the kings of gaming. However, in the last few years, they've become much more powerful in terms of graphics performance. Amazing? No, but I think it's good they're starting to focus more on it. The 15" Retina MBP has a 650M, which isn't terrible. The new iMac's have a few nice available chips, though expensive. I think this rumor could only lead to better computers, and more competition on the market.
