do CPU-specific optimizations make much difference?

Hi
Gentoo (a source-only Linux distribution) users frequently claim that their
systems are much faster thanks to the CPU-specifc optimizations they enjoy,
while e.g. Debian provides only i386 binaries for all Intel/AMD systems.
Are there any benchmarks available comparing applications like KDE, Mozilla,
GCC itself, etc. when compiled with e.g. -march=pentium4 as opposed to i386?
Thanks
Oleg
