I checked and we got both types.  We recently received some 3C906C, but
mostly 3C905CX. The first is a traditional-size card and the other is a
smaller-size card, the size of an Intel eepro100. They seem to be quite
equivalent, same drivers, same performance. I tested one of the 3C905CX
and it got over 10 KBps in a few cases, quite close to the nominal rate
which is 12.5 KBps for 100 Mbps. I can see no performance difference.

The 3C980C seem to be e new, server-oriented card, of the same class. I
saw it mentioned as a cheaper card in the Etherboot list. Also, that it
takes the same drivers as the 3C905C.  Well, looks like you can use the
3C905CX for clusters without any performance problems.
