>From what I've heard/read USB is fine for 2 tracks but not so hot for
more than that. In fact, USB 1.0 has bandwidth limitations. USB 2.0
probably doesn't (up to some limit) but I've not heard any good things
about handling more than two tracks. The best PCI card (with more than
two tracks) that I've seen at a reasonable price is the Delta 1010LT.
