So what are the model #s of this MB and the cards? What
 driver do these cards use? What copper gig cards are 
available, since most people can't use 10GigE interfaces? 
How are these x16 slots connected? I'd like to see test 
results you have to substantiate these 10GigE performance 
claims, since Matt wasn't surprised when my test showed
Dfly to be 15% slower than Freebsd 4.x.

I saw a car the runs on Xenon or something at a car
show. But it wasn't a real car, and its not terribly
practical even if it was.
