If you’ve gone PC shopping lately, you’ve probably noticed more
computers with 64-bit processors, and you may have wondered what advantages they
offer.
Put simply, a 64-bit PC can handle larger amounts of information than
a 32-bit system. Since it can use more RAM—4 GB and up—a 64-bit computer can be
more responsive when you're running lots of programs at once.
Which should you buy? If you tend to have a lot of programs open
simultaneously or need to switch frequently between programs—or if you just
want to be sure your PC can take advantage of the larger amounts of memory
available today—64-bit is a great choice. If you run only one or two programs
at a time or have older hardware and software that isn't supported by a 64-bit
PC, a 32-bit system is a good choice.
Whether you choose the 32-bit or the 64-bit system, Windows 7 is
ready.
