What is SteamOS?
SteamOS is a fork (derivative) of Debian GNU/Linux. The first version (SteamOS 1.0) is called 'alchemist' and it is based on the Debian 'wheezy' (stable 7.1) distribution.
The major changes made in SteamOS are:
- Backported eglibc 2.17 from Debian testing
- Added various third-party drivers and updated graphics stack (Intel and AMD graphics support still being worked on)
- Updated kernel tracking the 3.10 longterm branch (currently 3.10.11)
- Custom graphics compositor designed to provide a seamless transition between Steam, its games and the SteamOS system overlay
- Configured to auto-update from the Valve SteamOS repositories

^ Not sure it's worth it TBH.
Frankly I'm likely to wait a little longer. The big selling point of SteamBox/OS to me is streaming, i.e. using a non-powerful machine to stream from my main system. As it stands, there's no benefit with SteamOS in it's current state to using a gaming PC with Windows and steam in big picture mode.
After this work, Left 4 Dead 2 is running at 315 FPS on Linux. That the Linux version runs faster than the Windows version (270.6) seems a little counter-intuitive, given the greater amount of time we have spent on the Windows version. However, it does speak to the underlying efficiency of the kernel and OpenGL. Interestingly, in the process of working with hardware vendors we also sped up the OpenGL implementation on Windows. Left 4 Dead 2 is now running at 303.4 FPS with that configuration. (Source)
I'd expect steamos to be faster than stock Ubuntu especially on dedicated hardware because they are free to include specific patches to make things run better.
That's entirely moot - I know that as well as a linux gamer. I mean for day to day use, that's where a steambox's use lies for me; streaming games from a powerful box.
