Guru3D says the card is 43dBa full load... they can't hear it over the rest of their PC. Not sure what Kyle is doing different.

And the GTX470 is 20% better than a 5850 at 16x10 and 19x10 with 4xAA (as per the HWC review, and they tested with 10.3). It costs more ($50) but you get better FPS/$ but just worse FPS/watt.

So it is not a true "green" card :P
