I was asked this question today and frankly, I didn't know the answer.  
So I thought I'd post it here....

If you don't need to access greater than 4GB RAM, is there any benefit 
to running the 64-bit version of CentOS vs the 32-bit one?  That's 
assuming, of course, that the target machine utilizes a 64-bit capable 
processor.  I hadn't seen any noticeable difference, but I haven't done 
any benchmarking either.

On a desktop machine, the 32-bit version seems preferable since there 
are closed source creature comfort apps that are not yet available in 
64-bit land, correct?
