I do belive that the Phenom II gets very hot when you overclock it?
As does every other CPU when you overclock it. Increase power consumption, increase temps. It's not rocket science. Plus the OP is not interested in overclocking, nor does he need to be anyway. It's just for gaming
@asaflerman: Get the Phenom II 955 or i5 750 depending on whatever deals you can find and/or the price of other components like the motherboard. Both will provide a good solid gaming rig, overclocked or not. Forget i5 6xx unless you want to feel nostalgic for getting a dual core. Also, forget any i7 chips, they are a waste for anyone wanting a pure gaming rig.
