yah, i've even gone as far as to run a virtual machine and then run FAH on that too..
so i just fire up the beast at night or when i'm not going to be on it and i get 2 SMPs running at the same time..
it cranks out the 1400 point WUs at a very fast pace.. basically 2 WU's per day on average on that machine.
i'm close to the 500,000 mark now...
