I'm absolutely miserable in WoW, can't raid at all anymore(used to raid lots on this machine, but with each expansion WoW gets harder to run). So this upgrade? I'm actually ditching the videocard since the onboard will run WoW better than the videocard.
Intel's CPU performance is definitely better, but for me, without a dedicated videocard, AMD just makes sense.
Freezing could be a lot of things, could be heat related(check the fans on your CPU/Videocard) but since it seems you have that covered, the next thing I would investigate is PSU failure. Depending on a lot of factors, like how old the PSU is, what the original rating for it was, how much you've burdened it since you got it, it could be losing efficiency and browning out. It's really tough to say without more info.
I would love to see some CPU-Z screenshots of the various tabs of your system to see what you've got, and your timings, like the memory tabs, the motherboard, CPU, also the PSU serial number would be helpful, and when you bought it.
