I bought two of the cards in order to decide whether or not I wanted to use them in my research group's PII cluster. Right now, they're plugged into a 233MHz Pentium Pro and a 400Mhz K6-2 (using an Aladdin V-based board). I did a bunch of NFS testing over the gigabit link last week and didn't see any glitches.
The only "problems" that I've seen are (1) the round-trip latency for small UDP packets is at least 50% higher than FastEthernet on the same hardware and (2) the round-trip latency is highly variable.
