Depends on the specific CPU architecture. For AMD64, 64bit means
that you also get a slew of additional registers for gcc to use
for optimization for free. In my experience 64bit applications
have a definite benefit over 32bit on AMD64, the exception being
apps that are highly disk or network bound (I/O bound), which
don't benefit much.

AMD64 architecture provides more benefits to general 64bit apps
than broken 64bit sparc processors do. ;o)
