What you say is true, but it is possible to use two cards (or three) to
get more bandwidth, if and only if you wire all of your systems this way.
I wrote a BSD driver that round robined over multiple cards and got
30Mbits/sec back around 1992 or so at Sun.

Today, a better choice is to just use 100Mbit.
