Tip: be careful with overclocking. I ran my 5770 at 975 MHz for a week (up from 850) and everything seemed to be fine. The GPU temperature never went above 90 degrees C, which I think is OK. (I'm a GPU n00b since I'm not a gamer.)
However, after shutting down my computer for a few hours yesterday, I'm now getting garbage pixels on the screen, and random "verification failed" errors when mining, at all clock speeds. Looks like I damaged the card.

Yeah that is a high overclock, you kind have to expect your card to burn up without additional cooling. Im running my 5870 at 900 up from 850. I manually set the fan to 40% and the card hasn't went about 67 degrees. Now that is a good overclock.
