Adding "march" & "mtune" to /etc/make.conf

I read somewhere that adding the following to the /etc/make.conf file
would improve system performance:

	march=native
	mtune=native

Is there any truth to this? I an running 32-bit I386 Freebsd on a
64-bit processor. The main reason being that the is (was) no native
64-bit drivers for nVidia video cards. In any case, I thought 'mtune'
defaults to what "march" is set to so why enter both?
