Thanks Rick.
I submitted the benchmark to PI:

It's now top of the list for TR builds, 2nd overall to some Intel 28 core system.
And to re-confirm what I've said before - Linux PI blows Windows out of the water. The best Windows version I can find is on remarkably similar hardware to mine:
http://pixinsight.com/benchmark/benc...7T94Y1Q48I6377 and is only 2/3rd of what I'm getting. (Edit: it's CPU was overclocked to 4Ghz, I haven't done that)
Really recommend using Linux when using PI.
