100Base-T in full-duplex has max rate of 200Mbps, which would still
suffice...providing the NIC and the switch are good enough to keep up.
 I've not seen many NICs that can't handle 200Mbps, but I've seen
plenty of 100Base-T switches that can't sustain switching packets at
that rate.

Although, your PCI bus might get saturated.  Not sure what the limits
are there and don't feel like googling it right now.
