It seems a bit optimistic to me, that such a device can do what standard NICs cannot, but given that multiboxing on a single computer must mean lots of network traffic, you have to wonder if a dedicated network processor might actually help. I don't get much lag, if any, but I know that it could be 'smoother'. I am considering buying one, but I wanted to know if anyone had used it for multiboxing wow on one PC, and if it helped you or not.
