Voltage adjustment has grown to be a mainstay on most of ATI's upcoming 5000 Series graphics cards, and it looks like NVIDIA will follow suit with Fermi. According to Shane Baxtor from our affiliate TweakTown, it seems that NVIDIA will include the option on the GTX 480 to adjust the core voltage through the PWM chip. Although this may be limited by the GTX 480's stock cooler, it's more than likely that NVIDIA's AIBs will take advantage of this new feature and produce custom-cooled cards. I think that move is a positive step for us overclockers, it's always nice to get some extra juice out of a graphics card. Who knows? Maybe the rest of the Fermi line-up will include voltage adjustment too.
