Kotaku's Michael McWhertor pretty much says it all in the first sentence, "You may never buy a new video card again". The Game Developers Conference is in full swing this week and OnLive has been among the first of many things to be revealed and discussed this week. OnLive is a on-demand video game service that spits outs video games to your TV or low-end PC allowing you to focus on what games to play rather than what games will play on your rig. Much like playing games on a console for you stubborn "PC is better" people. The processing is done on their end while you receive the output via a video stream. Sounds alot like StreamMyGame, yet better implemented. McWhertor has done a great job of covering all the details as well as making the obvious cautionary statement about controlled environment demos.
Go get yourself some of that their knowledge boy.
