I'm interested in the benchmarks. My thing, though, is fitting them into my sense of real-world usage. I'm wondering about graphics performance. Given a Kubuntu install (no Unity crud, please, and turn off Compiz) on the system, would the following perform equal to that of a NVidia Geforce 280M:
Team Fortress 2, using the 280M's default settings, at 1280x720 resolution (720p).
Minecraft, default settings and size. I get roughly 55 to 135 fps through general movement in creative mode.
Everything else I think are covered by the benchmarks, including x264 encoding.
