I'm going to take another whack at 3dmark soon.
I finally cooled my GTX down a bit by adding an old slot exhaust fan under it (never realized that the GTX heatsink had holes at the base of it for exhaust INTO the case...). It dropped my temps significantly, so I'm going to overclock. I started small and its been running all night and gaming for hours at 600\1500\2000. I'll try pushing my CPU and GPU a little more over the next couple days.
