Thanks for the post. I've been considering upgrading my X2 4200 to a q6600, given how 5 boxing is pretty painful at times on it, even though it has an 8800 gts. If you haven't done this already, you might get even better perf if you use "junction" to reference a single wow install. There was a post I made about "pip performance" in the software section, and someone mentioned the junction tool. Highly recommend looking into that if you haven't already. It dramatically increased my load times. A LOT.
