Super overclock has significantly increased frequencies: 820/1640/3800. Stock for stock 580 appears to be about 15% faster in the (probably) 1920x1080 with AA and AF. But that Gigabyte is overclocked quite a bit... Gigabyte costs 469 at newegg. GIGABYTE Super Overclock Series GV-N480SO-15I GeFo... I missed the 580 $509 with 10% off deal at newegg the other day, so I wonder how the overclocked 480 stacks up against a stock 580.
