dunno -- i have the current GPU one for the ATI card running in tandem with the SMP one, so i can get one machine to crank out over 2.5K points per day with it..
i'd suspect the 8800 should work... it will be interesting, when it works.. cuz i have a PC with 2 8800's in it to run the multiple monitors.. maybe 2 GPU clients ? i can only hope

can't confirm though..
