TO OC YOUR GEFORCE LOOK HERE

[JTC]

I see alot of posts asking how to OC a geforce or what to use to OC a geforce. Well the best I have seen is the GTU (Geforce Tweak Utility) from this site :http://guru3d.com/ , under "downloads"> 'utilities". Not only can you OC your card, but all sorts of other tweaks independently for D3D and OpenGl.

NVmax has most of these too.

I find RivaTuner to be just as good if not better than both of those.
