If you consider 57MB/sec for a $45 card bad, then the ns83820's
are a bad deal. I consider that a good buy. CPU is around
30% of a P4 1.5ghz system, both sending and receiving sides.

It would be nice if the cpu was lower but it's acceptable for what
I do. (YMMV)

Also would be nice if Gbe switches were cheaper. Latest pricing I
see is $600 for an 8 port switch, or $75/port+$45/card for $120
per connection.
