I agree : there is no benefit in upgrading your
current OS .
You may be interested in reading something about
WOW64 & behaviour of 32bit based programs on WINDOWS
XP x64 AMD edition .


I was corious...so i installed it & now i advise you
against trying it : it will be a waste of time , as
you'll decide to come back , thus reformat 2 times in
one day .
Anyway , it's your choice .

You could also be interesting in evaluating this OS ,
