Currently, I have disabled the ATI Hotkey Poller service, so my video card is stuck at 2D speeds. Currently, I have very good framerates with 500/600, so I'm considering keeping it underclocked while playing a 3D game. At 100% fan speed, I keep 50 C in WoW or CSS. Does underclocking lower the life of the card? It doesn't seem like it would, but I want some professional opinions. Thanks for all your help.
