From ~x86 to ~AMD64

Hey group,

I'm thinking about replacing the old Pentium4 1,6ghz NW / Asus p4s333, with
Athlon64 3000+ / MSI K8T-NEO2-FIR.

I have a look at http://gentoo-wiki.com/HOWTO_AMD_64
where it says that "If you feel like gaming on an AMD 64 system you're
probably best off booting to a 32bit gentoo installation although a chroot
may work as well." Why is that?. As I understand, 32bit apps(and thereby
games) run fine on a 64bit OS?. Also,
http://www.gentoo.org/proj/en/base/a...?part=2&chap=4
describes how to create 32bit compatibility.......why will this not work
(properly) with Doom3 and UT2k4 ?

When converting, how can this be done?. As I'm not changing HDs, I hope to
be able to do something, that is as close as possible to a system
recompile.

Can I recompile kernel to match new MB, shutdown, plug in the new MB/CPU,
and startup. Then I should be running 32bit in the 64bit system.
Then unmerge the packages that don't compile on 64bit(like OpenOffice). Make
the appropriate changes in /etc/make.conf, and then.....?

Kind regards,

Stig
