Which drivers are you 6800 gt users running to be able to alter the clock frequencies? I have had a hard time finding later versions of the omegas..Any help?

U can use rivatuner but you dont have too!

My XFX came with the 'Coolbits' Registry tweek.  If yours didnt do a search on net and I am sure you will find it under 'Coolbits'

This will add your clock frequency to your cards control panel and you can clock it from there rather than a seperate program  8)
