Choosing a Processor

Because the CPU (Central Processing Unit), or processor, is the nerve center of your computer, it should be among your first purchases when building or updating a system. Whether you choose an Intel or an AMD processor, you'll have to make a choice about how fast a processor to buy and what bus speed to go for. Because both processor manufacturers are constantly upgrading their products, we suggest that you select a processor that is as fast and powerful as you can afford to meet your needs, so it won’t become obsolete as applications become more complicated and graphics intensive. However, if you want a computer simply for basic Internet usage, email and word processing, you can choose from some of the less expensive yet highly efficient models such as AMD’s Sempron and Intel’s Celeron processors. When selecting a processor, you must make sure it is compatible with the motherboard you’ll use in your system. CPU and motherboard compatibility is governed by the type of socket the processor fits into. For example Socket 754, Socket 939 and Socket 940 are designed to work with AMD processors while Socket 478 and LGA Socket 775 are for Intel CPUs. Whether you’re building or upgrading a basic system or you’re a computer enthusiast who plays games and loves outstanding multimedia entertainment, we have the processor that will meet your needs.
