Not knowing much in this area, but seems GPU related. If you are using the web driver, may be try to go back to the Apple driver, or upgrade OS / driver.

 

[Sharky II]

Yeah, definitely nVidia related!

My mac pro randomly reboots, I get this crash report on reboot, can anyone help to figure out what is going on?

The obvious culprit is the Nvidia driver and I concur with others that with a GTX660 you should use Apple drivers.

However, I see you have Soundflower installed and that can cause KPs even with Apple default video drivers. So if the problem persists after the driver change, then I'd suspect Soundflower was the real culprit and suggest that you uninstall it.
