Thanks for the tips Kraptor, I edited my files as you suggested and now PerfLevelSrc seems to be working - nvidia-settings shows powermizer performance level to be at '2'. So all is well on that front. In your initial post, you said I have to specify my driver as nvidia-new - when I do this, Ubuntu boots into the 'failsafe' low res mode complaining that it cannot identify my video card properly and the only way I can get back into X is setting driver as 'nvidia' - am I missing something or misinterpreting your instructions.
In any case, things seem to working as is for now. I really do appreciate you taking the time to help me - this has been a problem that has plagued me for a long time!
