Which 7850 for best OC?

[Jegergrim]

Hi I'm intending to buy a 7850 tomorrow, but I'm unsure which model overclocks the best, I've got my eyes on these so far (must be non-referance, since I don't have watercooling, and want to push as far without noise being an issue too fast).

Sapphire RADEON HD 7850 OC (2 GB)
Sapphire RADEON HD 7850 (2 GB)
MSI R7850 Twin Frozr 2GD5/OC (2 GB)
ASUS HD7850-DC2-2GD5 (2 GB)

Which one these overclocks best, and has best noise/temp/quality ratio?

Also I noticed some of these support 4096 x 2160 whereas some only support 2560 x 1600, is this relevant?

Thanks in advance //Jegergrim

Its not relevant unless you are going to be gaming or using multiple monitors hooked up to the same card.

As far as the best card, I have always been a huge fan of the Asus cards. One one can tell you how good a particular card is going to overclock since each INDIVIDUAL chip is going to be different, one from the next. A reviewer might have gotten a golden chip that overclocks to 2ghz (lol), but yours may not even get to 1.1ghz. So yeah, no way in knowing which card is a better overclocker.

As far as cooling/noise - once again, Asus is known for their excellence in that department.

You are probably going to have to read as many reviews as you can find and try to decide from there. And even then, something like overclocking is going to be more hit or miss regardless of others experiences with the exact same model.

Running at 1250/5600 stable with 50% fan speed and voltage at 1.22.

Buy it, it screams in BF3.

Yeah I think one then two of these is my next setup.

Powercolor Radeon HD 7850 PCS+, this card is running at 1000/4900 stock.

W1zzard overclocked it to 1245/6180 in his review here and it come with one of the best cooler on HD 7850 (Quiet & Cool).

Thanks for the input guys, I think I've come to the conclusion that i should buy the non-factory OC'ed Asus card, sine it has a larger cooler than the PCB, and should allow for better temps at higher clocks. Non-factory OC because these cards are already so easy to overclock. Cheers
