Everything still running well and stable. 3.85GHZ on the CPU, 850/4800 on the 5970, and 600/1600/1800 on the Physx with the PCI-E bus at 101. Running stable. Seems to be this config's limit... If only I had a larger power supply and battery backup. It says I draw 860 from the wall, though I am sure the monitor has something to do with it.
