Question regarding the Rev 2.0 of the Gigabyte 5700 XT GAMING OC 8G. I've got 6 of the rev 1.0 and 2 of the rev 2.0 cards running in the same rig. I've got the same BIOS Mod on every card, same OC and UV settings on each card. The rev 2.0 cards run at about 20 watts higher then the rev 1.0. It was also the same with stock bios and settings. Does anyone have any idea why this would be the case, what is different between rev 1 & rev 2?
