Personally, if you had asked this 3 years ago, I'd have said "Go i686" 
due to compatibility.
But now-a-days with up-to-date distributions there isn't many packages 
that aren't for x86_64.
Heck even flash finally got a x86_64 Linux version now :-D (Took them 
long enough though!)

Any machine I have that can run in x86_64, I normally install a x86_64 
OS, and recently,
I haven't found anything I need that is only i686.

And usually, when you *do* need a i686 package it's usually possible to 
install the i686
versions of the packages (depending on the repo of course) where a 
command such as:

yum install httpd.i686
(or .i386 again depending on repo)

would come in handy :-) and then you have the i686 version, though there 
not always stable
like that :-|

x86_64 has matured over the years and it's done it well :-)

But then, personally, I'd say, keep the current OS, unless there is 
actually something
that makes you actually need x86_64. As they say "If it ain't broke, 
Don't fix it".

Though if you build/acquire a new x86_64 box, throw a x86_64 OS on it :-)
But still, check make sure they are x86_64 binarys available. or sources 
that will compile
on x86_64. In most cases, it will.

Oh, and there's no such thing as a silly question ;-)
