Hardware: amd64, os: FreeBSD/amd64 and ...?

[Torfinn Ingolfsen]

I bought myself a new amd64 machine.
I intend to run FreeBSD/amd64 on it, and perhaps some other BSD's as
well. I'm not in the -current game, so I'll stick to -stable for now.

Would I gain anything by running FreeBSD/i386 (on another slice) on this
machine?

This is my first amd64 machine (actually, it's my first amd powered
machine), and I haven't followed the development on the amd64 closely.

Do most of the ports work on amd64?
Are there any other caveats?
