MSI 648 Max-F & ASUS A7V8X @Anandtech

Zitat

Worth special mention is the onboard Gigabit LAN. Gigabit is made possible by an onboard LAN chip from Broadcom, dubbed the 5702, the same chip the MSI 648 Max uses. While Gigabit is certainly a welcome addition to any motherboard, there's simply no need for this technology for most users, even though it offers 10 times the bandwidth of conventional 10/100 Ethernet devices (Gigabit offers approximately 1000MB/s of bandwidth). Gigabit is more useful for corporations looking to configure large, safe, and expensive networks, so most users (especially your average Joe Blow) won't benefit from this feature. Enabling Gigabit functionality was a breeze, it was no more difficult than setting up any other 10/100 device.
