[citation][nom]dansergiu[/nom]I think that Tom's Hardware should do a more technical article about this cards, some benchmarking and actually measure CPU load with and without the card in similar download conditions ( it's not hard if you think about it. All you need are 2 PC's - one server and one client the NIC on the client and simply download a 30GB file while running some 3d benchmarks ).[/citation]
Well, Tom's Guide did a great review of the Killer M1 NIC (Our first-gen PCI cards) last year:

As for the download test, we actually improve latency, while the Windows Network Stack is best tuned for file transfers. A better, more appropriate test would be to download a file while gaming, or download a file to the USB device while gauging CPU, system bus and HDD load. While gaming even.
And the best gaming tests are real-world tests. Two computers and a third server as the game server are fine for lab purposes when we test functionality, but it doesn't properly portray what a person feels or sees when they're playing from home. Two computers side by side connected to a crowded, offsite server in a busy game is a better test.
For our performance testing, and what we recommend to reviewers, we get two identical computers (1 Xeno, 1 no-Xeno) and connect them to an external server. CS:S is a good start, but we test a lot of games. Two testers play, while a third tester has a stopwatch and a score sheet. Every minute or so, the scorer says "time" and the testers read off their framerate and ping. Repeat as necessary.
Since gaming and networking are essentially random, noisy exercises, we gather a LOT of data. This could be 30 data points over 60 minutes or so, in order to smooth out the occurrence of random events (you could be dead, you could be looking at a wall) and get good results that will feed back into real world predictability.
Thanks again!
