Andy "gellehsak" Ryder of Team EG just did a review of Killer NIC's premier card, the M1. Basically, it claims to lower pings and raise your FPS with an extremely beefy NIC. The thing has it's own DDR RAM and a processor built in, which are put to use with a custom version of linux that offloads and optimizes work normally done by your CPU.

Screenshots (Q3, Q4, UT3) and more to see the results for yourself can be found @ http://www.myeg.ca/index.php?s=news&id=5813
