I already do it and it's great! Many of my favorite games are on Twitch, Starcraft, Path of Exile, League of Legends, and the best is probably Magic: the Gathering which has awesome tounament streams from StarCityGames and the Magic ProTour all day pretty much every weekend. Combined with a 52inch TV as a monitor, I have yet to plug in the cable into my TV that Comcast forces you to buy!
