If you're not interested in technical stuff, just right click on "My Computer" or just "Computer" and scroll down to Properties. There you can find out whether you're running 32 or 64 bit, and if not, it's 32 bit.

Main difference is, that in 64, you are not limited to 2GB of ram usage, which is easy to achieve with several bigger mods and big map.
