Yeah, it seems to work like that Stewii. A good way to test this would be to copy a file from one computer to another on your network, while playing the XBL. Obviously things run better if only your xbox is active on the network, but I don't know how much it would impact everything. Teh internetz come in at between 6 and 15 (usually), and your network can handle 80ish.

Guess I'll have to pick up a gigabit card for my PC!
