PCI-X can run at 100 and 133mhz but PCI-Express is bonded channels. For
instance a PCI-E 1x (1 channel)would be able to move half the data in a
given time as a 2x (2 channels)slot. The 1x or 2x channels still operate
at the same speed.

PCI-E is a whole new technology and rethinking of busses.

As far as a recommendation for NIC's, Intel is the one to beat but they
are pricey.
