Well, the first question is:  What does happen when I install the SSE3 version
(or how it's called) on my machine, use py2exe to build an app, and this
app runs on a SSE2 machine - degraded performance, or hard crashes?

I could probably live with the least performance, but not with the crashes ;-).

So, maybe the gui could allow to select whether to install the high-performance
version specialized for the current cpu, or a more portable but a little bit
slower version (I assume there is one included) that can be safely used for py2exe.
