SMC Etherpower-II adapters (based on thp epic/100 chip) are quite good.
You may also want to look at the quad-port DLINK board (based on the
DEC 21143 chip, I think it's the DFE620 but I'm not sure) if you're short
in PCI slots.

Netgear has a 1000baseT version of the GA620, which can also do 100BaseTX.
This may also be a good choice, and leave you room for future expantion.
You'll want a motherboard with 64bit PCI slots if you use theses :)
Also, the GA620 can do IP/TCP/UDP checksums on board, which offloads the
CPU and reduce latency (the if_ti driver doesn't use this yet, but it's
still on my list of things to do - At last offloading IP checksums to the
board should be quite easy).
