Hi mate cheers for the reply.
Well it seems to work very well anyway no problems what so ever, I was just wondering about the settings in the nvidea control panel as its not that clear what some of them do..
But using its defaults works fine. I use a qudro at work and its nice to have the application control feature where you select your 3d app in a list which turns on the best settings for the particular software package.

cheers mate
