To set this straight, no, not a computer-thingy.
Steam is supposedly working on their own linux-game-platform-computer-thingy, no?
Valve has a Linux version of Steam and they're porting a large number of AAA titles, treating GNU/Linux (as opposed to Android/Linux) as a primary target platform. EA is also doing the same. Unity3D is now supporting GNU/Linux as a first-class target platform. These three cornerstone companies on the gaming world are getting full technical support from people like Canonical (the corporate backer of the Ubuntu distribution), who is working with the likes of nVidia to get the video drivers fixed appropriately.
I met with engineers from Valve and Unity3D last week to discuss what's necessary for Ubuntu. It's real.
