For a sub hundred dollar PC, we don’t expect it to perform like a gaming desktop. Rather, we are surprised that it runs a game like Skyrim at all.
Game Stuffs has a video showing Skyrim running on the Stream 7. It averages 20-25 frames per second at a very low resolution, but this is still remarkable considering hundred-dollar hardware.
In the comments, Game Stuffs tells us that the Stream 7 will not run GTA4. The Stream 7 will run GTA3, Vice City, and San Andreas though.
