5 x GPU options - please put into performance order

[jmp_78]

As title suggests really. I obviously know how the AMD cards compare to each other, and the Nvidia against each other... just not sure the difference between SLI vs Crossfire scaling. Thoughts on 1st to 5th place would be great - thanks

6850 Crossfire
6870 Crossfire
550 SLI
560 SLI
560 Ti SLI

May I ask why you have chosen the cards you have? Are you thinking of buying one of them in Xfire/SLI?

Possibly... that said, I am well aware of the 1GB VRAM limitation of all cards listed. I've just been bitten by the 'wanna try 2 cards' bug even though I always thought it'd be far more hassle than 1.

For the record, I'll be getting new full system soon as current P55 board only supports 8x/4x Crossfire

Thanks for the advice guys, but I don't have the funds to buy 2 x 6950s, plus have been offered £105 for my current 5850 so aren't too bothered about getting another.

I guess my question should have been... 6870 Crossfire or 560 Ti SLI?

Thanks Surveyor, appreciate links. Defo getting new board in new build, and for the record I play at 1920 x 1080.

Thanks again
