The Motherboard - this is one of the most important parts you will buy for your computer-to-be. The type of motherboard you purchase will depend on its intended purpose of computer - be it an inexpensive computer for the kids, or a high-end computer for video gaming and video-editing. If you plan to use the latest CPUs, you’ll need a motherboard that is compatible with it. You have to take particular care in choosing pick your motherboard because it will determine the limitations of your computer. For example, if you want several USB ports, you have to make sure that your motherboard can handle that.
The CPU - If your motherboard does not include a CPU, you’ll need to select one that fits your motherboard’s pin configuration, and a clock speed that fits your budget and preferences. If you want to build a high-end computer, I would recommend you use a dual processor (Intel Core 2 Duo). The Pentium 4 processor is another a good choice.RAM chips significantly determine how efficiently your computer runs and affects how many programs your computer can operate smoothly at the same time. For optimal performance, buy at least 512MB- 1GB of RAM.
