oh thought you might want to see these benchmarks. just saw them now.
they benched marked running fedora core x86-64:

I was actually looking at a different set of benchmarks:
Ubuntu: 32-bit v. 64-bit Performance (on AMD 64):
http://www.phoronix.com/scan.php?page=article&item=616&num=1
The conclusion reads "Looking over the results 64-bit Ubuntu was able
to provide a strong advantage in the GCC benchmarks with both LAME and
the Linux 2.6.19 kernel compilation. However, a slight advantage had
remained with both Unreal Tournament 2004 and the LAME encoding tests
in a 32-bit environment."
The merely "slight" advantage enjoyed by 32-bit Ubuntu (over the
64-bit version) appears encouraging. However, the test machines (and
the Intel benchmarks you listed) are for machines with much better
specs than mine. I was under the impression that you don't get good
performance from a 64-bit distro if your machine doesn't meet a
certain hardware minimum for RAM and processor speed.
