Where Can I Buy a Used CPU?
The CPU, or Central Processing Unit, is the brain of any computer system. All data processing occurs in this module and the ability of a computer is largely determined by this device alone. For those looking to upgrade their CPU units, remember to pay special attention to the configuration of your current system as an old motherboard is not likely to support a top of the line CPU. Additionally, some brands support only Intel CPUs while others are made for AMD processors.

Finding the right choice
-
The needs of a consumer are largely defined by their intentions with their computer system. A graphic professional, movie editor or music production professional will require a fast system capable of running several intensive programs at once, while a user running primarily business applications does not need an expensive or especially powerful machine and will spend most of their PC budget on expensive business software. Determine your needs with your CPU and always check the power and price of the CPU against your personal computing needs.
Performance
-
When there is no alternative but fast, the right CPU will have multi-core capability, a high speed, and it may be overclocked. Overclocking is a process by which CPUs are manually adjusted to allow more information to pass through quicker. Overclocking may have detrimental effects on the CPU or other hardware systems in the computer, so if a machine is not designed to be overclocked, do not attempt to do so. Overclocked used PCs are available on the market at special, high rates because the service is a skill performed by knowledgeable technicians. Specialty computer stores and electronics pawn shops are likely to carry powerful, used CPU systems.

Affordability
-
When looking for a used CPU, affordability is generally a large part of the equation. There are tons of affordable options from major processor makers like Intel and Advanced Micro Devices. The older a chip is the more inexpensive it's likely to be. When shopping on a budget, make sure you have a good idea of how old is too old for the software you want to run. This can be determined by looking at the minimum requirements for your programs. Additionally if you plan on multitasking, a cheap dual core will be much more conducive to your work than a high powered single core.
Shopping eBay
-
EBay is a large source of used technological equipment from private and commercial sellers. The most important part of shopping on eBay is ensuring that the seller is trustworthy. If they have had a lot of recent customers and have a user review of at least 95 percent you can feel pretty comfortable about trusting their services.
Other Online Options
-
There are many electronic distributors with e-stores or online extensions of their storefront businesses. If there is a trusted distributor you have used in the past, check for a web address. For large orders, websites may offer free shipping and handling or even product upgrades at no charge.
Pawn Shops
-
If you prefer not to do business over the Internet, or have an immediate need for your CPU, visit a pawn shop. People often sell their old computer systems when they become obsolete, and pawn shop owners can disassemble the machines, saving what pieces are still technologically relevant. Check out nearby pawn shops for the used CPU you would like to purchase. Often these stores offer especially good deals.
Computer Resellers
-
Computer equipment stores have a large selection of options, but will generally charge more for their expertise and variety. Additionally, for those who aren't themselves amateur technicians, these stores often offer installation services and options like overclocking and wire management. If your having trouble figuring out the CPU to look for, start at a computer reseller, just make sure you weight you options and check out the rates of other stores.
