Im just wondering, most of the nForce4 boards that have on-board gigabit ethernet are using Vitesse, with maybe the exception of the DFI boards. I wanted to know whether the Vitesse VSC8021RX is using the PCI or the PCI-e 1X bus. I couldn't find the information from Vitesse website, although I managed to find the product. Also, does on-board ethernet effect system resources?
