if you still have this card could you just run an quck test on XP or vista with the Folding GPU2 client on it whats the PPD and per frame time as well you get on it, as no one has posted its ppd yet (not that i have seen)
XP/vista turn off aero and any thing that does 3d affects as the Nvidia CUDA mite BSOD the pc if any thing animated happens as the GPU2 does anlot of work but does not give prioryty to windows 2d/3d performace
vista 64 support bit picky at this time
