Personally I'd go for single 580, 560 SLI or 6950 CF are also great options.

I'd rather have 78% (techpowerup@1920x1080) the performance of 6950CF with no potential dual card issues.

thx for the help guys,
im leaning towards the 6950 in xfire,or would a single 580 be better?

 

[straxusii]

A single 580 would be slower (78% the performance)

thx strax,
thought i would go with 6950 xfire.
have always gone with nvidia so the 560 sli is really tempting.
will look for through reviews of 6950 v 560 before i decide,again thx for your help.

I would get 6950 crossfire and then flash them both to unlock shaders, just don't flash them with a 6970 bios

I have one of these, and, no word of a lie, have been running Crysis over three screens with 2xAA, and everything else set to high, with decent frame rates. Getting a second soon so I can max both that and metro
