Crossfire 6870 + 6850?

Hey Gamespoters, I was wondering how the performance is for these two cards in Crossfire. I'm not too familar with CrossfireX power scale and I can't find many reviews with these two cards.

Anyways, I'm upgrading my friend's computer and he currently has a AMD 6850. He wants to Crossfire another 6850 for Battlefield 3. The reason I'm asking is, because the 6870 is just 10 dollars more >.>.

well the 6870 will be downclocked to match the 6850. You will get the same perfomance as 2x 6850. But you can oc the 6850 to get a nice boost in perfomance.

yep basically you will have 2X 6850. why dont you go ahead and get another 6850?

just get another 6850

also where are you looking...you can find the 6850 for $130 after mail in rebatehttp://ncix.com/products/index.php?sku=62433&vpn=HD685XZNFR&manufacture=XFX&promoid=1337
