None, really...

A 6970 is slower, and a 6990 is considerably faster.

2x6870s are about 5% faster than a single GTX580.

So, you say 6970 < 2x6870 < 6990? So, according to this, http://www.tomshardware.com/reviews/...rd,2964-7.html

2x6870 = 5970???

this is correct. the scaling of xfire 6870s are amazing. if you google some benchmarks up against more expensive single cards, you'll see that they either match or beat the performance.

however... the VRAM is the only downside.

What for? what games will you be playing and will you play in eyefinity or single monitor? at what resolution if it's single?

I mean 2x6870 are enough to max out BF3 for example.
In my opinion it's better to get a 6950 now and then when you can cf two 6950,that way you will completely max any game out there,besides they have 2gb of vram whereas the 6870 has only 1gb,at high resolutions it does make a difference.

HD6950 is newer and 2x6950>2x6870 and more ram for high resolutions.

2 hd 6870 = 1 extremely overclocked 6970.

2 HD6870s are a bit faster than an HD6970.

If you can get a 2g version of the 6870s then you will be much faster than a 6970 on high resolutions. Also if you can snatch a 6870x2 an xfire it with a 6870 then that would be the sweet spot.
