Thanks guys. It is not a high load server, so I think sticking to i386
sounds like my best option.

Since a Xeon Quad Core is a 64bit processor, would it work ok with
FreeBSD? Or would the adm64 release be better for that chip?
don't be suggested by "amd" in port name. it's for AMD64-compatible

You'll have to remove and re-install all ports to make them 64-bits as well.

Not really. You could do a cross-build to another partition, but you'd
have to have one available.
Another poster seemed to indicate that the i386 release would run just
fine on a quad core chip.
Would there be a major performance gain with amd64 over that of the i386
build on a Xeon Quad Core?
It will depend on your workload. If your machines were strapped fo
address space on i386, switching to amd64 (with enough RAM) will help.
In "long" (64-bit) mode, amd64 compatible CPUs have more registers
available, so that will speed up things. On the other hand, pointers and
longs are 64-bit numbers instead of 32-bit, which will make the code
somewhat larger. Run some benchmarks that are relevant for you on i386
and re-run them after you've switched to amd64 to know for sure.
I've been running amd64 since 5.4 on both Athlon64 and recently Core 2
Quad without problems.
