OK, so i built a computer for a customer this weekend, it was a XFX 6950, the corner of the power connector was filled down, then i boot into windows, install the newest drivers from amd's website and the drivers wont recognize the card, so i research online and find the hotfix and finally got it to work. AMD's drivers are still lacking, and the corner filled down just did it for me. Absolutely no reason to pick up the 6900 over the gtx 570/580, im not a fanboy, but i do prefer nvidia from my 15 yeras in the computer business.
