I am trying to choose a hour for a gaming rig and trying to choose between two cards. The asus 6850 and the gigabyte 6850. They are the same price and the only difference is clock speeds with the asus sporting 790 Mhz chipset and 4Ghz for the asus and 820Mhz chipset and 4.2Ghz memory speeds for the gigabyte. The gigabyte has higher speeds but the asus has many more reviews and better rep. Thanks guys
