Some more thoughts:
-Managed to get my 8800GTX upto 4200PPD with nothing major running.
It's now down to about 3000PPD with 2x SMPs at 75% at 3.37GHz on a Q6600.
The SMP clients haven't updated yet, so I can't post their PPD values.
-I still can't figure out how to find the GPU usage. Rivatuner doesn't show it, and neither does GPU-Z. Either that or I'm a noob and can't find it.
-The Display SUCKS. I've BSODed more times in the last 12 hours than I have in my life. (Unless I'm trying to CAUSE a BSOD) I've managed to crash 2 separate machines just by opening the Display.
-The GPU client eats CPUs for breakfast, lunch, dinner and a midnight snack. With nothing else major running, it was bogging down my machine.
