Yes it runs at 16x and 4x. There will be a noticeable drop in performance using 2x6870.

If you want the max out of your cards, getting a new board would be optimal.

Was a bit too fast on that one, thought you had some old Phenom. My bad.

Anyway, yes Crossfire will work without any problems, however, you will lose performance by not using 2x 16 ports.

A single card solution is really your best choice.

you will not lose that much performance actually. id say less than 5% so it's still pretty good. go for it.

You could sell your 6870 and buy a reference 6950 for under $300 to unlock into a 6970.

I'd say his best bet is selling his 6870 and go for a 570. However Xfire 6870 will work just fine on your board, but if you're one of those wanting to get the most out of your cards, a 570 is your best bet imo, and even the cheaper 6950 is a good choice.
