Re: GTX 260/280 Clock Throttling While in 3D Apps. An Explanation.
I do this via RT on my 8800gtx and its a great idea. It does $ave power, reduce heat output, and my PC runs quieter (can't hear it) when not gaming because all of my fans are under temperature-based control. Not doing this and running your card at full OC 24/7 is, well, stupid and pointless.
