See this thread:

"We also achieved nearly 80 Gbps in bidirectional TCP tests (40 Gbps
simultaneously in each direction):
This was using 2 dual-port 10-GigE NICs in the first two PCIe 2.0 slots.
We are using an Intel i7 965 quad-core 3.2 GHz Nehalem processor
(overclocked to 3.4 GHz) and 2000 MHz DDR3 memory. Adding an additional
dual-port 10-GigE NIC on the Nvidia N200 chip does only marginally
better, as it appears we are basically CPU limited at this point for
this test (the sum of the TX and RX CPU utilization for each pair of
10-GigE interfaces is about 93%). "
