Man, OCUK replace a 5850 & 5870 for these cards, 6 series sucks, Cant even get 400 mhash out of them. Junk. I understand OCUK's position on price difference but they ARE NOT A DIRECT REPLACEMENT (6950 & 6970 respectivly) and the 6 series isnt nothing on the 5 series
bummer
1.3V is max by the way on 6870
