Well, it might seem a lot, but your memory still has enough room left.
You say it has 432 mb free, but on my system it usually has like 15 mb
free (even on 2GB systems). This is not because Fedora takes up so much
memory, but because files are being cached in memory. If the need arises
that programs need more
memory, it will free up this space, and allow programs to take it up.

I'd double check "free" again, and look at the amount that cache is
taking up.
