Amd sorts the chips according to quality and then rates them for speed. If the "cushion" that they give is taken into account, then the 800 would stand a higher chance of 1000. We still have to accept that the aluminum interconnects are "only" capable of around 1000, maybe 1200 with heroic cooling efforts, so the gain may in fact be marginal. (say a 600 can go to 950, a 800 should go to 1000) We are all taking the "luck of the draw" by expecting a 50% increase in processor speed anyway.Perhaps the "luck of the draw"was more valid before 700 and 800 were out because all the chips that rated at 700+ oem were still labeled 600.Now that they can sell these higher speed chips for more$$ they will. My 600 reaches 950 too, and maybe the best point on the subject is that there is almost no difference between 900 and 1000. (But we all want 1000 don't we?)
