I've never seen CPU utilization be a problem except at Gigabit speeds.
Unless you're creating a very high-end router or have very limited CPU
resources the bottleneck will lie elsewhere, IMHO.

I see another poster has recommended Intel NICs. I'll second that. The
e100 and e1000 drivers in the stock Linux kernel are (or at least were
originally) supplied by Intel. IMHO it's hard to beat vendor-supplied
open-source drivers in the kernel.
