Oh, ok, that makes sense. I had 8 active processors one week, because I was working on a friends PC, (rebuilt it), and stress tested it with F@H for temps... and had to re-install everything on my gaming rig after breaking my HDD...
Anyways, how do you have your dual client rig set up? Both CPU's or 1 CPU, 1 GPU? I would guess you (hopefull) got the GPU client crunching.
