It's a common myth, but it's never really been true, even in the days
of big shared Ethernet segments. On a modern switched network, you
should really be able to get over 95% of the nominal bandwidth,
although I wouldn't want to run VoIP that close to the edge without a
lot of QoS tuning.
As for the original topic--it's getting hard to find good 100baseT
cards these days--I used to buy Intel EtherExpress Pro cards, but
they're hard to find. I've had good luck with Intel's GigE cards, and
they're only $50 or so. That's not exactly cheap, but they seem to
work well with Linux. Most 3com cards are okay, too, but I've had
better luck with Intel.
