Boris,
Three issues:
1. Motherboards that still have PCI slots have bridge logic in the chipset,
which uses a driver. I have encountered a situation in a Gigabyte board
where the PCI performance was substandard. The symptom was extremely low
throughput on an Ethernet card. If you choose PCI-e, you bypass a possible
problem.
2. If there are two PCI cards, it could be said that the PCI interface is
inferior, because it shares bandwidth.
3. On the other side of the coin, PCI-e Firewire cards have gotten some
pretty bad reviews. Check Newegg.
Sorry the above does not lead to a conclusion. The most respected card here
in the U.S. is the ADS Pyro, which happens to be PCI. If you can't get it,
be sure to get a TI chipset -- that's really important.
