My System Specs

Default

Theoretically you cannot pass 4 GB with a 32-bit system since the maximum signed bit allowed on a 32 bit system is 2,147,483,647 (aka 2 GB) however you must also count -2,147,483,647 making it a total of 4 GB. If ever you want to pass that number then the signed bit will change into a negative, making it impossible to go higher.

Honestly PAE doesn't provide any advantage other than make the number go higher, the performance won't improve since the amount of virtual memory is the same.
