Over the past 20+ years, the PC industry has revolved around key innovations in processor technology. Recent years have been marked by the emergence of multi-core processor technology. Today, there are essentially three types of processors currently available for the desktop PC user: single core, dual core, and quad core. The ‘core’ is the part of the microprocessor that does the work. This is different from computers with multiple processors.
Overclocking is the process of manipulating the CPU and other components of your computer to run faster than the manufacturers rated speed. Why would you want to overclock your computer? Overclocking can improve performance in tasks such as resource-intensive games, programs running large databases, extensive graphics editing, and video rendering. The budget conscious could also save money on their processor by purchasing a cheaper low-end CPU that can be overclocked to higher specs. And there’s always the bragging rights of having that really fast, super-tweaked system.
