will it be both running 16x/16x or 16x/8x / 4x

also if i buy a 3870x2 how well will it perform?
please don't post the same thing multiple times.

yes, it is possible to crossfire 3870's on this board, they will run at 8x/8x.
it's hard to say how an x2 will perform without knowing what the other parts in the system are, but i'd be willing to bet the performance would be comparable to crossfired 3870's.
