The story so far:

As you may know, Valve, now a member of The Linux Foundation, has initiated some ambitions projects: the SteamOS, a Linux operating system optimized for gaming, the Steam Machine, a gaming colsole that will run with SteamOS and the Steam Controller, a game controller specially designed for SteamOS and the Steam Machine. A demo video of the Steam Controller can be found here.

The first Beta version of SteamOS 1.0 (which has been released in November, 2013) is a customized Debian Wheezy system, running on Kernel 3.10.11, back-porting fresh Nvidia, Catalyst and Mesa binary drivers, uses SysVinit as the system’s default event manager, a personalized GNOME 3.4 as the default desktop environment for the Big Picture mode and Xcompmgr, a lightweight graphics compositor.

While the Nvidia graphics cards were supported by default, Valve has recently patched SteamOS to officially support both Intel and AMD GPUs.
