Unless if you have a fetish for SX (optical) networking, I'd go with a Broadcom 5701 based card such as the HP NC7770 for any system with a PCI bus (except the O2).
Requires a bit of hacking of driver or card (all documented here), but they run well, they run cool, and they're on eBay for as low as $2.45
