Not bad. I did the same to my ATI x1900 XTX. O/C it still runs Crysis fine, and if it can do that, I am good to go for pretty much any other game. My stock speeds at 648/774. O/C I am at a safe temp with speeds of 688/792. It gets me to 23 FPS for full detail mostly w/ DX10 light sourcing, etc. in Crysis for the GPU test (which is not a valid in game test since it stresses the card by moving fast over highly detailed terrain - something that won't happen in game, not even when flying the aircraft in game), which means in game I am over 30 FPS constant.
If i can manage that, it is not quite yet time for a new GPU yet. When i start chunking in some game, then I'll buy a new GPU. I'm milking this one for all its worth because I originally paid $600 for it.
