That is good! Just done a new test but beacuse I am installing things it has gone down! I think I am at around 8.37ish.
I am tempted to push it a little further but happy with where I am at...coming from a Q6600 I hope the gaming experience will be very much a different story!
I really need to upgrade the HDD's as I am using about 5 - 6 year old ones so not too snappy!
You went with my spec if I remember? 5GHz stable straight out is pretty amazing. You will probably get some throttling above 1.5v on air, so it'll be worth tweaking it later to try get and volts lower and temps down.
If you've got it, try something like Crysis 3, the performance increase will be enormous.
