There are alsu a ((very) small) number of ports that do not compile or do not run in 64-bit mode. Figure out if one of them is mission-critical before installing; check for the "NOT_FOR_ARCH" and "ONLY_FOR_ARCH" settings in the port's Makefile. That said, the machine I'm typing on is about six weeks old and running an AMD Phenom II x4. I installed amd64 with some trepidation, fully prepared to re-install i386. However, it's now up over 675 ports - including apache, mysql, firefox, and OpenOffice - and everything works.
