Hi, i got one of the PowerColor x850xt from OCUK ofcourse
and at stock its 520 / 540
i swapped out the stock cooler for a nice Arctic Silencer, that dropped noise and temps by about 1 third !!!! was well impressed, then upgraded the bios to the PE version.
Ever since then i have been playing games, then overclocking a little more, bit by bit and then testing and so on, using AtiTool for o'c and fan control.
At the moment i have it at 605 / 585 without any problems, and it just seems to keep on going.
When just in the desktop i have underclocked it by 200 for both gpu and mem and it can actually idle at 55 with NO FAN going, completely passive.
How have other people found these cards for overclocking?? mine just seems to keep on going for ever lol, best £150 i ever spent.
