I just read the crossfire FAQ and had a question about the PCI 3.0 x16 slots on the mobo, and supporting of crossfire

Will I see less performance gain in games like Battlefield3 because of the fact that my mobo doesn't have 2 x16 3.0 PCI-E ports?

Is the mobo good enough for going crossfire on 7950s?

I assume it should be fine since there are 2 3.0 slots. You can do it in the following: 2 (x16/0 or x8/x8)

As long as it fits, it'll work.

Even if they were 2.0 slots, it would work fine (backwards compatible) Hell i'm using a 2.0 card in a 3.0 slot.

Im waiting for the 7950 to drop before they release its replacement and i may consider getting 2 myself in this very same board. Personally they always recommend just getting the 400 dollar card which would be the equivalent of 2 cards since:

Less power
Less configuring
only 1 point of failure instead of 2.

However i always like having the option of adding a second card which is why i bought the -V board and it supports full 16/0 on 2.

Ok, thanks for the reply.

So you're saying I won't notice much difference? I kinda knew that it would work :p , just wondering performance wise, if it would be much of a difference.
