How much extra can you usually (key word) get in performance? Min/Max? That is to say my crappy Powercolor 800GTO oc's stable to 459 and I feel comfortable with 456, it is a stock 392. Is a stable 470+ out of the question? Is it worth the effort on a card with a 3dmark06 score of 760, I can't buy a better card right now. What about the Laser Cut for the extra four pipelines if possible, how much do those extra four give? Is this worth the extra work?
