factory overcloced cards are all relative, but the best out are sapphire vapor-x, zalman vf1000 and the MSI coolers.

sapphire & msi aren't released, the zalman is an aftermarket cooler.

My friend has the Sapphire reference cooler OC'd(900MHz) and he can get it to run at 985(1000 for 3D Mark) and 1200 on the memory.

my diamond is sitting at 985/1125 stock cooler no problem
temps stay in the 50's with 35-40% fan

Different manufacturers run different default voltages as well, I believe the powercolor and XFX cards come closer to 1.4V stock though I could be mistaken.

Someone could verify this by posting up their GPU-Z screenies of the card under load.

fair enough. not necessary to get any other kinda cooler then, really.

you could always get one for the noise factor, if i wasnt gaming it would be distracting , but i play with headphones so it not to bad, fan at 100% is really loud

Nope my xfx 4890 had 1.3v stock on load, Had to bump it to 1.45 to get 1000/1100

How difficult is it?

I just looked at the egg and the sapphire is $219 with $20 MIR...tempting! So I was wondering if you could flash its bios to the Asus one and use the voltage tuner for some awesome OCing .

Thanks

you can use things like gputool to increase voltage, provided it's a reference model. The powercolor pcs+ version has a non-reference design and no volterra chip so I don't think software voltage adjustment is possible.
