KillerNIC is something as odd as a high-end network card designed for gaming. It has been questioned in many ways, so we decided to test it as thorough as we could imagine and then bring out some statistical calculations to get some scientific proof. We've summarized 2,400 ping values together with FPS statistics from 40 test sessions in this review. And yes, it does work. Sometimes.
"There is perhaps no other product that is more controversial and generates more heated debates around the 'Net than the Killer NIC. It makes big claims, and the difficulty is that traditional testing methods may not give a full representation of the card's abilities. As a result, I've spent weeks testing and exploring the Killer's resulting impact on lag, framerates, and responsiveness, running it through the paces, gathering massive amounts of data."
