I've been using Gentoo on an amd64 machine for about 2 years now. The amd64 
should include the same steps you'd need for the Opteron; just change your 
-march setting in the cflags (covered in the manual). Personally, I find that 
the selection of applications is fairly even with x86. You can look at what's 
available at packages.gentoo.org. I actually used SuSE-64 when it first came 
out and was strongly disappointed; been using Gentoo since day two of owning 
this machine.

It's always good to know your system, but the entire installation process is 
rather painless (minus my experience with Grub which isn't architecture 
dependent). You'll want to learn more about the CPU if you plan on developing 
for it, but as a user you should be fine. You'll learn a lot simply by using 
the environment and reading up when you can or run into problems. Anyway, good 
luck with your install whichever distro you decide to use.
