After a bit of dinking around, I got my CPU OC'ed from 2.81 to 3.05 and I've turned up the clocks on my video cards by about 80MHz.

With running 3DMark06 now, I scored 11682 over my stock score of 10893. I've gained about a 7.5% increase in performace....I'll see about pushing things further at a later date.
