LOL, didnt know that. I read about this once a while ago, but forgot.. I just thought that with all of the heat and added transistors from a bigger chip, ATI just had a harder time running it at an equally high clock. Remember how the 6800 Ultra ran at only 400MHz compared to the 5800 Ultra at 500 MHz?
