As for 100mbit cards:

Hands-down, Intel 'fxp'-driven cards... rock solid in terms of 
performance and stability; never had a single unit go bad, used hundreds 
of them, including dual and quad-port cards.

On the gigabit side:

I've had great luck with broadcom cards using the 'bge' driver, and a 
few intel cards utilizing the 'em', but nothing real extensive or 
saturated enough to authoratively say they work under extreme pressure 
or anything. I've got a couple of dual-opteron servers here with dual 
on-board broadcom gigabit cards that have ben running flawlessly for 
over 2 years now, (uptime 378 days on one, the others were rebooted 
several weeks ago to be relocated to a different rack). Knock-on-wood, 
no panics or mysterious network outages as of yet - so I'd say they're 
fairly stable - but again, never end up near saturated over here to give 
you an answer on performance.

Anyhow, just my two cents - if you don't need gigabit, ya can't go wrong 
with Intel 'fxp'-driven cards :)
