Installing a 64 bit OS or keeping a 32 bit OS?

64 bit builds are generally a little faster.

Whether you will notice this or not running normal 'desktop' apps is 
debatable, but you should if you do any heavy data processing. For 
instance the data analysis application I work on runs 30-40 % faster 
when built in 64 bit mode, over the same code on the same machine in 32 
bit mode.
