Do you have refresh rate forced to match your real refresh in Compiz?
Do you have "detect refresh rate" disabled in Compiz?
Those two settings will greatly effect your Compiz experience. Plus, turn on VSync in the nVidia tool.
I'm using my 9650M GT at the moment, with multiple windows up, refresh at 60Hz, Compiz forced at 60Hz, detect refresh rate off, and all window movement is silky smooth.
