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.
On a similar note, I moved my 2900xt into the bottom PCI slot yesterday in preparation for Crossfire. Even though there's only one card in my system at the mo' it runs at 8x speed in the bottom slot.

I had to reset my HR-03 in order for the Crossfire bridge to work. The good news, previously I could run it at 870/1200 for benching. Now it's running at 901/1200 (1.3v PCIe 115mhz idle 50c load 65c). Whether it's improved airflow/reseating I'm not sure. What I can tell you is PCIe running at x8 didn't bottleneck the r600 at all.

Here's hoping Crossfire X runs on this board
