How fast? As at 4.5Ghz you could run bigadv for about 95K + ppd. BUT thats a 3hr margin to deadline running 24/7 obviously, and possibly in linux.
But i think smp is around 40ish maybe. You will need to see what the hit is running a gpu, i don;'t think its a good idea.
For a comparision...I'm getting about that on my 2p @ 3.1Ghz in a linux vm. I'm swappping o ubuntu this weekend and running it dedicated for bout 110kppd .
