I'm not really familiar with that particular card but I doubt you will
get real "pro" performace from it. The analog circuitry is inside the
computer so even if you can use 24 bits the last bits will probably be
just noise. I think it also shares the same internal architecture of the
SB Live in the sense that all processing is done internally at 48KHz, so
if your sources or destinations (even analog) are 44.1KHz the card will
do resampling for you. You can only get clean digital transfers and no
resampling if you work at 48KHz. That may or may not make a difference
for you.

That should not be a problem, I think. I think they will not use system
resources (ie: irq's, dma channels) because no driver will be available
on linux. As long as you have enough pci slots it should be fine.

Linux can coexist with WinXP or Win2K (install Windows first, then
Linux). I don't know if WinXP can coexist with Win2K, I imagine it
should :-)
