Thanks guys for the feedback!

I overclocked my processor tonight by about 20% but it did not seem to make a difference at all to my wow performance... If the problem with running the multiple clients is with the processor I would have guessed even the 20% would make a noticeable difference.

Perhaps the issue is my videocard? Or maybe the 64bit windows???

Can anyone recommend software for overclocking the video card? It looks like the catalyst software will do it - maybe that is good enough for the job. I don't really know that much about overclocking a video card. I am assuming its similar to a processor where you get some benchmark software and keep turning it up until you find the sweet spot.

Stupid pumpkins....

If I can get it down to 70-80% usage that would be fine - I dont mind lag in Shat I do mind lag when i fighting bad guys. Also - I am assuming northend will be a fucking disaster if i am having lag issues in outlands.
