I was very happy with the performance of my new 4870 @ stock, but then I installed Crysis Warhead and... well, you know. Especially the ice levels really bring on the slide-show at 1920x1200 so I'd like to overclock the 4870. Have already swapped the cooling to a Accelero S1 with 120mm fan that keeps the temps at about 55 degrees after an hours gaming (<40 degrees at idle).
Now, where do I begin? Have never really overclocked a GPU, but I remember reading there was some ATI tool (CCC, or ATT possibly?) that tests different setting until the card stars artifacting. Then I guess you can reduce the overclock by 5% for good measure, and you're off. Not planning to do the BIOS volt-flash this time around, want to see what I can do at default. Rest of the system is in my signature.
I'm sure there's a good thread someplace that someone can point me to - thanks!
