I'm not sure if the Sempron 3000+ is even 64-bit capable.
Well, I have played with the LiveCD part of AMD64 Ubuntu Feisty DVD (a
4GB download) on my Sempron 3000+. And I didn't notice any difference
with regard to OpenOffice and Firefox. But I haven't tried any 3D
games (there are none on the DVD AFAICT) or encoding media files.

There's not much benefit if you'd run it in 64-bit mode and have low
memory as applications would need more memory (due to an inverted page
table addressing scheme when you run in 64-bit mode), aside from you'd
still need 32-bit applications to run some proprietary software.
My goal is simply to future-proof my setup. So it's okay if I don't
see any immediate "benefit" from going 64-bit. My main worry is if I
will suffer a performance penalty under my current setup. Are the
hardware requirements of 64-bit Linux similar to Vista?
As for 32-bit proprietary applications, I don't think I'm using any at
the moment. I'm using the Xorg ATI drivers, don't have any particular
need for Macromedia/Adobe Crash (until Gnash matures), and use MPlayer
(with the open-source FFMpeg decoders rather than the hacked MS DLLs)
for all my exotic multimedia needs (DVD playing, streaming media).
