I have a dual monitor system but I am a gamer as well. So I cut off the second monitor when I am playing games (though display pref though i am looking for a good program through which to do that) but it seems that i am still losing some performance with the second monitor contected but not being used. Should that be the case? Is there anyway to minimize my loss. Or do I just have to live with it.

Also what is the best tool for OCing my 9800pro?
