Yes, if you compile them natively on AMD64. Whether this results in speedups depends on a lot of factors. Instruction words on AMD64 are longer than i386, so binaries tend to be bigger, but on the other hand you've got more general purpose registers. The general consensus seems to be that you _need_ AMD64 if you routinely run out of address space. In other situations it can be nice to have, but it depends on the apps and the workload. I've been using an AMD64 system as my main desktop machine for years without problems. There are some ports that won't work, but that's mostly x86 binaries like the flash plugin and nvidia drivers. Both of which I can well live without.
