Valve have announced a new product called Steam Link, a streaming device that will "extend your Steam experience to any room in the house," according to a press statement.
Link will work with Windows, Mac and Linux computers as well as Valve's much more robust console-like Steam Machines, so long as they are all linked to the same home network.
Streaming will support 1080p resolution at 60 Hz and with "low latency".
Priced at $49.99 and set for a release in November, the device includes three USB ports, HDMI out and is set up to be easy to use according to the PC gaming giant. Worldwide pricing will be announced at a later date, as will whether the release date is international.
Valve's Steam Controller will also launch in November at the same price, to support the device hoping to bring PC gaming into the living room (or bathroom if you really wanted).
Steam Machines – contained set top gaming PCs made with a variety of specs by different manufacturers - were announced last year as part of Valve's on-going initiative to encroach on the home console market dominated by Sony's PS4 and Microsoft's Xbox One.
Steam Link is a cheap and effective facet of that master plan.
Steam Machines will also go on sale in November at various price points to be determined by the various manufacturers.
Also at GDC, Valve announced Source Engine 2, revealing that it will be made available for free.
