Dont want to have to change the motherboard because I would also
probably have to get a new flower fan and possibly memory.  I thought
the Athon64s were not being made any more (dabs.com in the UK don't
sell them) but will look into this further.  How long does it take to
encode 1 hour in nuvexport in the default settings (multi pass) where
not a lot else is happening?
