Getting a little "hitching" in WoW on my new 5870

Further to my post above r.e. Quest Helper and other WOW UI mods, QH has a performance setting that throttles back it's load on the CPU if it proves to be the culprit. Type QH /perf 50% to throttle back the overhead a bit. I run QH at 20% of it's usual tracking load on my machine.

I don't play wow anymore, but try playing with processor affinity.

Also I know wow uses 2 cores only by default, I once found a way of making it use all 4 cores.

Here I think I found it: http://www.nvnews.net/vbulletin/showpost.php?p=1773548&postcount=2

Try making it use more cores, or forcing it to use 3 cores by changing affinity and than run your other heavy stuff on the remaining 4th core. It may help.
 
When I do this on my i7 860 WOW crashes and the operating system often blue screens. Approach with caution.

Is your 5870 video card overclocked? If so consider overvolting your video card to 1.15v and see if it gets rid of that. I had a flickering issue with my overclocked 5870 but it disappeared after I set it to max VDDC with the AMD overclock utility.

+1 to that, with my 920 I set it to use 8 cores (255 I believe) and its automatically using the first and third core instead of just the first and second.
 
With no stability issues ? When I set mine to 15 I get crashes in WOW pretty darned quickly and more often than not the computer blue-screens shortly thereafter.. W7 64bit.
