[mythtv-users] 32 vs. 64 bit, any significant difference?

[Brian Wood]

Building a new backend, and trying to decide whether to go 32 or 64 bit. 
Obviously it's a 64-bit CPU (AMD FX-60).

Only using 2GB of RAM, so that's not a factor.

I know it's been asked before, but reviewing past posts I don't seem to see 
any final conclusion.

Normally I'd go with 64 bit, but I wonder of there are any reasons to go 32 
(Flash players, XBMC Boxee)?

Thoughts?
