I currently use the standard ethernet LAN NIC card, that runs for about $20. I notice there are $80 NIC cards that have their own controller built in, relieving the main CPU of some duty. Are these much of an improvement???

I am running an Athlon XP2000+ system. DSL. Ethernet modem and router. I use it for general internet use, for which I am not concerned about speed....and for gaming, in which I AM interested in performance.
