64bit vs 32bit Operating Systems, which one to choose having 2GB RAM? [duplicate]

"32bit.

There'll be a marginal RAM usage decrease, as pointers are 32bit not 64bit, and you'll have slightly less driver issues in theory, and I'm really only saying 32bit for that. Go 64bit if you ever plan to upgrade, as the disadvantages are tiny, especially as 2GB of ram is still a fair amount, you shouldn't notice the few extra kb of ram taken by a pointer-heavy program."
