For F@H computing, NVidia finally has a chance at being productive

Here's my findings so far with GPUs:
Nvidia 780: 81000-120000 (Depends on what workunit I get)
ATi 7970: 100000
ATi 7950: 79000
TomTommy: EVGA GTX 670 FTW 2GB: 56000 to 110000
ig0tik3d: Sapphire HD7850 2GB: 30736
ATI HD 7660D: 30563
melnikalex: 7950 @1000 = 85000 on Celeron 1610 2.4Ghz DDR3 4Gb
7950 @1000 = 75000 on CoreDuo E4300 1.8Ghz DDR2 4Gb
Sondey10mg: Sapphire 7850 2GB: 30632
If people could post what PPD rates they are getting on different GPUs, I'll add them to OP, and update the tables for my guide(s). Another consideration is PP/$, or Points Per Dollar. The ATi 7970 seems to be the best so far. As people can see, each card has an operating range, since different work units have slightly different rewards and optimizations for select hardware.
