If you’re looking to increase your wired LAN speeds, it will probably be cheaper and easier to get an mGig-capable switch that is separate from the router. This will handle all of your LAN devices at up to 10 Gb/s, and you can uplink the switch to one of the ports on your router. For the most part, your router really only needs to support the speed of your Internet connection. Any local traffic between wired devices on the LAN will never traverse the router.
