I've seen reviews that have shown a 260 GTX (216) able to match a 280 GTX when clocked to 660. With a simple bios mod you can increase the voltage to 1.18 and top out at nearly 800 MHz.. something you can't do with the 280 GTX because it's already at it's max volts. So in theory even an overclocked 280 GTX that was able to reach 730 would still only be about even with a 800 MHz 260 GTX. You'd need to do a physical vmod on the 280 and that's starting to get into needing better than stock cooling territory. Then of course there's the price dif. of over a $100... To top it all off I figure DX10.1 is being skipped in favor of DX11 with windows 7... so there's no loss there. I can just use the crazy clocked 260 GTX for physx and get a nice DX11 card when windows 7 rolls out. So for $250 or lower this card (with a tweak) seems to be the most impressive card on the market once you look at all the factors... anyone else agree?
