I'm working on a game with it at them moment, but would like to get some kind of estimate of what kind of specs my game would crawl / work / be fun / fly with.

I know I could make the blend public and ask, but I'd really like to be able to see results from a wide range of machines without spoiling surprises early.

I was (/am?) really hoping we'd see Yo Frankie become a test suite. Even just somethng that gave out the numbers from Blender's own performance stats (Framerate, %CPU load - Rasterizer / Logic / Physics). Failing that I'm guessing that some combo of the PTS tests would help approximate, but I'm a bit lost as to which ones...

Thanks all! PTS is looking like a great tool. With Ubuntu / Arch inclusion and a Gui on it's way, I have a feeling we're seeing a real leader of the pack rising.
