I'm using Vista 64 bit with sp1 and it works great (2x30" monitors). The short freeze ups stopped when I started using 1 or 2 wow directories instead of 5. And I threw a 10K raptor in there and I totally forgot about freeze ups. The vista drivers in general are getting much better.

Also with a raptor 10K hd stuff loads so quick it's nuts. I'm almost always AV raid lead - not sure if that's because I'm the first to load or what.
