I would have to run it at stock to really tell you that. Only had it at stock long enough to let Windows do its thing with the new CPU, and after that immediately went to 3.6 GHz, rans a few tests and tried a couple of games and then took it to 4.0.
I can tell you that there is a very noticeable difference between the 955 and the x4 630 (that was running at 3.4 GHz) that was in before, in games and such for the short time I had it at 3.6. And can see and feel the difference at 4.0 over 3.6.
