Actually, I apologise for my earlier slam against the ASUS Z96F. If you're using USB audio, this thing is excellent.  By Wednesday I should be able to report how well a FireWire ExpressCard works on it too with FreeBoB.

Although this thing's firewire chip and firewire interrupt assignment sucks, the interrupt assignments for USB are pretty good. Only one USB port is on that awful everything-shared interrupt; the other four USB ports are each on pretty much their own interrupts. USB performance so far appears to be excellent. 

So it seems that ASUS (or Intel, whomever made the decision), optimised this machine for USB, not for firewire.

I'm using an old M-Audio Audiophile with it right now, -n3 -p128, and it's fantastic.

NB: the Z96F is US$400, barebones. That's pretty cheap. I added 2GB RAM and a 7200RPM drive to it, and a T7600 Core2Duo CPU.
