This would depend on what you want to find out, the total memory, the
amount available to the system and what is allocated for the user?

The physical memory available to the system after removing sharing
like a video card taking up some memory.

The memory available/allocated for the user(yourself)

The total amount of memory (not including sharing, like video card)

Hope this helps.

Please correct me if I am wrong, but that is the way I interpret the results :)
