caveat, dc supports a lot of chips, some are good, some are junk.
definately excellent are the original DEC (now intel) 21143s. Still the 
best 100 MBit/s chips ever built I'd say.

however, if you're buying new NICs now, I'd suggest getting GBit 
ones... most of them have the ability to offload more shitz to the 
card, especially the checksumming, which I have seen to make a 
difference of over 10% in CPU usage with real world applications.
Some even implement checksum offloading correctly - you wouldn't guess 
how many fuck that up... the intel gigabit cards are a safe bet usually.
