Hey Bob,
If you are using the 5.1 ND drivers, it is disabled by default and that solved my Quartz Extreme not supported problem. If you are using these drivers than there truly is a problem with the Nividia. The 5.1 Drivers caused problems and the 6.0 caused problems until I unchecked the desktop display option.
