The othere advantage (which the OP wasn't suffering from) is the issue of
the 32-bit kernal not reserving enough of the Virtual Addressing Space for
device drivers (by default) when you have large amounts of RAM (typically
more than 768MB). This is common when combining certain capture cards
and the NVIDIA propriotary driver. This can be fixed by telling the kernal
to reserve more virtual memory (reducing the amount of RAM the kernel can
address directly), but the problem goes away completley with the 64-bit
The way I see it, if you have a choice, use a 64-bit kernal, as there is
very rarely any harm in doing so. Is it worth the upgrade, probably not
unless it is the easiest solution to your problems.
