If by better you mean 81.05 to 81.60 then yes, it is better.

But really, that's the first time I've really tried using Afterburner in a bench. Up til now I've just been seeing how different clock and fan speeds affect temperature in Kombustor. I do have some questions though.
1. I've unlocked voltage control in the options, but they're still both greyed out.
2. The core clock bar tops out at 875MHz. Why does it do this and would I even want to try and push past that?
