Probably one of the biggest Bang for your Buck (on Linux) would be to recompile your libc and OpenSSL with -march=native. Then at least all software that depends on those libs (probably the majority) would get some benefit from your local processors extensions.

Or you can use Gentoo.

glibc and OpenSSL both have runtime detection of CPU features to switch between hand-coded versions of hot functions, so those two are probably the packages that will get the _least_ benefit from a recompilation.
