NIC's with Samba?

I used to have 8139c cards in my home machines, on a switched 100mbit network, including a Dual P3 server that I run 4 x 80G drives with a HPT454 RAID5 array (software I know, but the dual P3 copes admirably), both the server and my main desktop (dual Athlon MP 2600) were getting to the point of being unusable when such high CPU useage when transferring large documents (Quark files, uncompressed TIFF's etc., saving was becoming a nightmare - 30-45s to save a 60mb Quark document!) ... I ripped them both out and replaced them with Intel PRO100/S Server adaptors.. they're about £25 each and the cpu use when transferring large files is a fraction of what it once was (2-3% in Windows task manager).
Those Realtek cards are now sitting in machines that my family only use for web browsing... and with ADSL, they still taxes the cpu more than they should, in fact, I'd hazard a guess that a couple of old 3C509B ISA cards would probably hit the cpu less.
