Might as well get the 5850 coz the price is approx. the same. Don't quote me on this but won't a single 5850 use less power than 2X 5770?

I would get the fastest single card possible than 2 crappier cards and Xfire them...

As Zero said, there are some Xfire issues and profiles and stuff.

I think it's not worth the hassle. Plus you'll get bragging rights for the 5850 :)
