To further derail this thread, my system behaves quite peculiarly in the area of the Pagefile.

I run a Q6600 X38 system with 8gb of ram on Vista64, but while even running only 1 copy of wow for under 2gb of total memory used, I still see page faults and up to 2gb of pagefile usage while running only 1xWoW and Vista.... it's been pissing me off for over a year now. [/derail]
