Since you're only seeing 3.12 GB with a 32 bit OS you would get almost a
full gig more with 64 bit. That would improve performance if you
sufficiently load the system - you would be able to run more applications
before the system would have to start using the page file. An important
issue is whether or not the BIOS supports memory mapping above the 4 GB
address space. In order for the OS to use all 4 GB for itself and
applications the memory addresses for hardware need to be moved up.
