Q: Would I benefit from using a 64-bit computer?

A: A 64-bit computer can process twice as much information as a 32-bit computer, and can have significantly more random access memory (RAM). This makes a 64-bit computer a good choice if you are working with video, large database searches, or games and other programs that require complex calculations and a lot of memory. A 32-bit computer works very well for most programs, however. For example, spreadsheet programs, Web browsers, and word processing programs run at about the same speed on either a 32-bit or a 64-bit computer.
