This is what I get for the GPU after playing 10 minutes of a simple card game. (88C) I can't imagine what it could be playing an FPS Game. This is on an imac i7 2011. I never had any such high temp before in SL. I would say 75C max in SL running extensive GPU benchmark during an hour. Now only 10mins and I got something way too high. I know imac could handle high temp, but I'm not so sure about this one for a long time without damaging something. Have you guys got such high temp on the latest imac?
