I had the exact same experience, wow was it fast.

As for compilation of Boost, some libraries do generate a large 
hit.  For example the lambda library.  However, I find Microsoft 
pre-compiled headers make a huge difference.  Just make sure to 
use manually created pre-compiled header files and not the 
automatic option.

BTW, this is very easy to do with MPC 
(www.ociweb.com/products/MPC).  Just create files called 
{whatever}_pch.* and MPC will do the rest.
