Coming in to GDC, all signs pointed to the death of Steam Machines. Not necessarily the concept, but at least the "Steam Machine" name.
Reports of that death were premature, it seems. Valve unveiled an entire "second generation" of Steam Machines this week, featuring partnerships with Alienware, Falcon Northwest, Origin, Syber, and more. Systems of virtually every price point and configuration were represented. The bid to drag PC gaming into your living room is on.
We've got full configuration details for every model here, as well as our impressions, here.
