Does your audio device really work OOB?
My doesn't. And sleep doesn't work. I have Sabertooth P67, BIOS 3302 too.
My DSDT has SSDT injected and all pstates added from x16 to x48, so my 2600K on 4.8GHz gives 17100 points in Geekbench.
My DSDT for 2500K with default clocks is here, and for a CPU overclocked to 5.0GHz is here.
Also there is a patched BIOS 3302 to work natively with apple power management.
Also, to work in Mountain Lion over 1.6 GHz including OC, I need to set Turbo Boost multiplier to Per Core in BIOS, but not All Cores.
