Alright, so I've got an ATI x1600pro pci-e, and I've overclocked it to what I have been told is a pretty high clock speed, and I'm still artifact free! Right now, my core clock speed is at 604mhz, and my memory speed is at 436mhz, and the card runs around 70*c under load. I ran 3dmark06 before overlclocking, and scored an average of 1500, but after overclocking I scored at 1831, quite a bit of a jump if you ask me. So, what are the rest of you OC'ing your x1600pro's at? Are my scores pretty good considering the card I have? I think my gpu can go farther, but I don't want to push it too much w/stock cooling.
