Want to make their head explode? In some experimentation a while back, I
measured latency of packet processing of an old Netgear FA312 100Mbps
NIC in a P3 450Mhz, verses an Intel 1Gbps PCIe in a Q6600 quad core. The
Netgear had lower latency, and IIRC, significantly lower latency. Of
course, all those measurements were in microseconds, and therefore
probably irrelevant to actual gaming, but I don't think they actually
care. The length of the cable was measurable too at that scale. (If you
get pictures of a fight breaking out at a LAN party over old 100Mbps
NICs, and who's sitting closest to the switch, send them to me
please :-) )
