Hello, I have an iMac, late 2011 27" 4gb ram, 1tb hdd, 1gb graphics 3,1ghz i5 (not sure about the last one). Normally, using os x, it doesn't heat, even when using high end applications. But when I use windows 7 via bootcamp it heats seriously. And I just use it to play Titan quest. Not a very high end game. Is that normal? I'm thinking of using my iMac to play gw2. Won't it heat?
