You guys w/ 9650s are killing me. I wish I could afford one of those.
Anyway, here's the best I can get on my Q9550, 3.9GHz. Any higher and I have to push the vcore through the roof (1.55+). Passed p95 for 7.5 hours small FFTs and 3 hours of blend. Paired w/ the Raid0 SSDs it makes for a lightning fast system, so I have no complaints.
