DominiKing, use RivaTuner and do a bit of research to find out what clocks others are getting with your config just to get an Idea where you should be at.
ATITool is a great program for ATI cards but I have found RivaTuner to be much better when working with Nvidia cards.
PS : I think the latest version is Beta 2.06 and is by far better than any of the previous versions.
Good Luck man
