So running a 32-bit OS, you won't be able to use all those 4GB, but a
bit less (say 3,5GB).
But again, keep in mind applications running in 64-bit mode uses more
memory, so you won't gain a lot here.

If you want to, install a 64-bit system, if you want to be absolutly
on the safe side go for a 32-bit OS.
Most likely you won't regret any of those choices.
