Processor/ CPU

The processor is the heart of the computer, when any data is first given to the computer the cpu processes it and sends it to the required components, such as the sound card. Processors are measured in how fast they can process data, this is measured in Ghz (gigahertz 1,000,000,000 hz ).  So the faster the processor the better, but also newer processors are more efficient, so a 3ghz processor made today will be faster than a 3ghz processor made two years ago. The best way to find a processor for you is to look at some benchmarks and compare it to other processors, make sure it is relatively new and has a high clock speed.
