Best dual gpu combo

[savan1221]

ok so i am probely going to get this mobo
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130564&Tpk=msi%20870a%20fuzion

and only two gpus so which one would be the best bang for buck

two 6950
two 6970
6970 and 9800gt
two 460
two 560
the thing is this mobo can run nvidia and ati together so which would be the best combo

6950 and 460/560
and are there any other mobos out there that has same functionality and also if only doing just amd crossfire which would be the best value mobo to overclock 1100t to at least 5ghz

The rest of your specs?
Budget?
Monitor?

1080p monitor and as cheap as it can be

I would recommend getting a SLI or CF instead of a Lucid board because the drivers are still immature and as a result,it doesn't perform as good as either SLI or CF.
Between the options given,2 6950's would give you the best price/performance ratio IMO.

5870s are an option also that you should consider..

i would say 2x 6950s and then unlock them to 6970s, thats the best bang for buck. also 2gb of vram is really good when crossfiring because you dont get double the memory when crossfiring.
