They showed benchmarks, and the performance gain was negligible.... ESPECIALLY for a network card well over $100. Plus a lot of the features it has, like prioritizing packets from games over packets from other applications, are available on newer motherboards using the NVidia Network Access Manager. Pretty much the only benefit of having one is saying "I have a dedicated network processor with it's own cache memory"..... which will probably only benefit you if you're trying to make yourself the biggest laughing stock on any tech forum.
