Buying a personal computer can be as difficult as buying a car. No matter how much one investigates, how many dealers a person visits, and how much bargaining a person has done on the price, he still may not be really certain that he has gotten a good deal.

A computer has only one purpose; to run programs. Some programs require more computing power than others. In order to figure out how powerful a computer the consumer needs, therefore, a person must first determine which programs he wants to run. For many buyers, this creates a problem. They cannot buy a computer until they know what they want to do with it, but they cannot really know all of the uses there are for a computer until they own one. This problem is not as tough as it seems, however. The consumer should go to his local computer store, and look at the software that's available. Most programs explain their minimum hardware requirements right on the box. After looking at a few packages, it should be pretty clear to the consumer that any mid-range system will run 99% of the available software. A person should only need a top-of-the-line system for professional applications such as graphic design, video production, or engineering. Software tends to
