You can keep the 32 bit system.

As I understand it, the graphics memory is allocated from the main 
memory at startup and the allocation is permanent while the system is 
running.

I'm not so sure what you mean here - if you want to know if you have to 
reinstall after adding some memory, then the answer is no. The system 
finds out how much memory is available at each startup and uses the 
available memory.
