I have been thinking about doing the same (at least, recompile kde, qt, 
postgres). Gentoo users insists that recompiling gives a big perfomance 
boost. A friend made a test comparing Fedora against Whitebox and get amazing 
results running sql queries agains Postgres.
But somebody told that sometimes, recompile would just give a slower package.
