Tyan has boards arriving in their USA warehouse as of the 15th of December.
PCI Express is especially interesting in HPC as many of the advanced 
network boards are now coming out in PCI Express interface.
GbE and Infiniband already, and Myrinet, and others soon.
As we have already hit the wall of PCI-X with these devices, Express 
adds a significant improvement in bandwidth and latency.

Opteron HTX will add even more performance when it come out in 2005.

The main reason I posted is that I thought it significant that the first 
Opteron dual board with PCI-Express is finally out.
