Not a heat issue, I can run Crysis at 1920 x 1080 max setting without the temp going very high, I have 6 fans in this comp ( I custom built it myself) it runs very cool all the time.

I actually beleive my issue is the fact that it is windowed (I've had wow lock up a lot when in windowed mode, no idea why)

But now that I thought about that maybe I can try PIP and see if that fixes my issue.
