My understanding is that there is presently nothing to be gained in  
MythTV from going to 64 bits. I ran a 64-bit AMD Gentoo system for a  
while, and compiled MythTV from E-Builds, but had a lot of trouble,  
none of which do I believe is related to 64-bittedness (is that a  
word ??)

AFAIK all of the MythTV "distros" (ie: releases which install a more  
or less complete MythTV system on your machine) are 32-bit, even if  
you install them on 64-bit hardware.

Your AMD processor should do a good job (I'm using a 3700+ clawhammer  
core) but running in 32-bit will not hurt you at all. You would be  
better off upgrading your storage if you want to improve your Myth  
system (although you don't mention what storage you have, it can  
always be improved :-))
