Steam Machines. Maybe you've heard of them. They're Valve's oft-talked about, rarely seen in the wild solution for streaming PC games to the fancy HDTV in your living room. And at GDC this week, the company brought us closer to the promise of that commercial reality with a display of all the various units you're likely to see hit retail by November of this year. As Gabe Newell told us, the variety of Steam Machines on offer, from the low-end $50 Link to the premium $5,000 Falcon NW Tiki, present a "good, better, best choice for consumers." But enough talk -- I know you just want to see the goods. So check out the gallery below for a trio of the Steam Machines Mr. Newell demoed for us, as well as a video just after the break showcasing an expanded selection coming later this year.
