My opinion is to first determine a few issues.

How much RAM will it need?  If over 3GB of physical RAM, consider 64  
bit.
Are there third party applications you need to run on it?  If they are  
64 bit, that answers the question too.  If 32 bit, are they supported  
on 64 bit OS?  Do they have different versions for 32 and 64 bit?
