I have most of my peripherals wired, not for the sake of being better at games or anything, but i just prefer it, i got tired of changing / recharging batteries.... Though running cat6 downstairs from my router just so i could hook my roku and media PC up when i could have just used wifi was probably a bit silly. But if i didn't rent id wire up every room for ethernet and build my own PF Sense router with a separate firewall so i can have all my outgoing web server stuff on it's own network, because why not.
