Dual 7770's in Crossfire or 7950?

[chimpbagel]

I have a question about 2 video cards:
Should i get the dual HD 7770 in crossfire or a single 7950?
The CPU will be a fx-8350, 8GB of ram and 650 watt PSU.
I want to play BF3 in HD on 60 fps and want to play black ops 2 at medium in HD at 90 fps.. and planetside 2 in HD (..ofcourse...) at 50+ fps.

Thanks

where to buy a 7870le ?
And what are the problems of a crossfire setup?

Also, not every game will benefit from multi-card configurations. Go for the 7950.

I would choose a 7950 by far!
