I dunno, it seems GDDR5 development have been stunted in the first half of 2009, with all of these economic malaises, the production ramp up and speed development have not been as fast as it should be. Considering nVidia can sell a more complicated card with 448 bit buswidth with such a low price, i think 384 bit buswidth PCB isn't necessary all that expensive. Naah, it's just a wet dream of mine, nevermind.
