It turned out that shadows fixed it and I'm now running all five on my 8-core just fine with combined processor utilization hovering at about 45% in Orgrimmar with no more hitching or slideshows. I also just found a GPU widget so I'll be collecting stats on my GPU load and memory use.

I won't be chucking the 8-core setup because I use this machine for audio/video production. It was never designed to be a gaming rig, but since I had the horsepower and the video card, I decided why not

Huh? Where did you get this information, because it doesn't make sense. While I understand that gaming motherboards garner higher performance scores because of their overclockability, I don't see how a dual-cpu capable motherboard will somehow have its GPU PCIe lanes running slower to somehow make room for disk or network I/O.
