Poor performance from a high-end build?

Has anybody thought about looking at what they're network card is doing when they get slow FPS?

Yeah I think I know what the network card is doing, it's receiving incoming packets and sending outgoing packets. Micromanaging your Internet traffic if you've got other applications running that require Internet. I am sure this is what my network card is doing when I get low FPS.
