While I've been on the 64-bit bandwagon for a long time (15 years),
there are still issues. I totally agree with Andy. With 32-bits you are
essentially limited to 3GB of memory, but if there are driver issues
with both your sound and network drivers, I certainly would recommend
32-bit temporarily.
Additionally in some benchmark testing I did a few years ago, there are
some applications that run better as 32-bit than if they were built 64-bit.

There are, however, some additional advantages of 64-bit systems. First,
there are 8 additional registers available in 64-bit mode. I think you
should see better graphical performance in 64-bit.

All in all, as a desktop workstation, as Andy mentions, you should not
see any significant benefit with a 64-bit OS, specifically in light of
your problems.
