Personally, I haven't particularly noticed any speed increase because I used a 64-bit OS. I have had both FreeBSD and OpenBSD in 32-bit and 64-bit environments, but the only speed increase I have seen is through an SMP-enabled kernel and some other things like better graphics cards or more memory.

Just because the system is 64-bit doesn't mean it will be any faster; it's more of a programming issue. Really, all that 64-bit hardware gives you is a larger addressing space. It could possibly mean more speed if 64-bit addressing removes some bottleneck in a particular application (this really helps in high performance computing and large servers), but in general, there probably isn't much of a difference when comparing an AMD64 desktop to a standard x86 PC.
