Here you might have a problem... If the cards are not identical, even for
good-functioning cards, you will probably see differences in timing of
sending and receiving packets which will lower the overall performance of
the "cluster". I haven't heard of such clusters, normally the
desktop computers are taken from a lab where all computers were bought at
the same time and thus have identical hardware...
I think that in your case the only solution is to invest some money in
some good network cards for all the computers that will be used in the
cluster.
