True. Cable and DSL modems operate at 10MB/s, so a faster NIC on that side won't help. However- if your hub is 100MB-capable, the NICs on your internal network should be as well.
Moving 4Gb of data from one box to the next accross the network can get to be a real pain at 10 base-T. However, unless this was a rather pricy hub, its probably only a 10 Base-T itself. Also, as far as 10 Base-T cards go, you've got some of the best ever made.
