nvidia control panel for gtx680mx on iMac

Hi,

I baught the late 2012 iMac and was wondering if Apple provides the all features/software for the NVIDIA GTX680MX that it comes with. When NVIDIA drivers are installed on the PC, the drivers that are installed on the system have the NVIDIA Control panel and the settings specific to the video card to tweek the video settings. I dont see them on the system prefrences or anywhare. I do not see any Mac/OS X drivers on NVIDIA'swebsite either.

Cheers,
