Processors

It began with the ENIAC, a 30-ton monster about the size of a railroad freight car. In the six decades since those early computers, electronics have changed frequently. In fact, some say that PC hardware is obsolete almost before you buy it. Fortunately, computer hardware is available, allowing consumers to upgrade, rather than replace, their computer systems.

What is a CPU? The central processor unit (the CPU or simply, the processor) is part of the motherboard, the heart of a computer. A laptop computer, desktop computer, PDA: every one has a motherboard CPU. Their speed is listed in GHz (gigahertz) these days, and the higher the number, the faster the computer works. So, when do you need a CPU upgrade? You need a new CPU when your computer isn't running fast enough. Also, when the CPU upgrade is affordable. The longer you wait, the lower the price, unless, of course, you shop at Overstock.com, where we never wait to lower our prices.

Sometimes, you can do a CPU upgrade only. In some cases, a new motherboard will be your only option. Some motherboards can be so expensive and complex to switch out that buying a new computer is cheaper than replacing the current board. Look carefully at your personal situation and research your processor options. Then choose the option that meets your needs and let Overstock.com help you meet your budget.

While you're making this major change, consider a minor change or two: If you're getting a faster CPU; why not a RAM memory upgrade to go with it? Likewise, computer power supplies wear out eventually. If you are going to open the patient up, you might as well do all the needed surgery at once.
