I have two (32-bit) AMD Athlon MP 2800's (an older Tyan motherboard,
the Tiger MPX). It still performs very well though. I will try
swapping PCI slots, though this seems to be more related to the
software side of things, because as I said when I use just the analog
i/o (the first 8 channels, i.e. hw:0,0) and not the alsa multi plugin,
Jack suddenly becomes ridiculously rock-solid (it's actually *hard* to
get xruns, even running at 64 frames). Such a vast difference in
performance almost has to be software related, probably (as the
previously linked web site mentioned) something clock-related but then
I don't know much about what's going on at the driver level.
