Here here... Rumormill is w/ the engineers that 3Com plays some tricks (on the edge of the specs) to get some extra speed, but the tricks are not entirely compatible with specifications... that is, they make some assumptions which other folks (like Cisco) don't make... and this is what eventually gets them into trouble as described below. Of course, they totally scream if your entire network is 3Com because every xcvr takes advantage of the same tricks.
The Intel nics (our choice) are "dead by the book" and as a result tend to be absolutely stable,... generally we do not see performance problems with them either. So far, all performance issues we've seen with Intel nics turned out to be trouble elsewhere on the Lan - like topology issues, hubs, switches, etc...
