If you are a computer buff you might find the dual processor vs dual core article an interesting read.

Dual core processors setup has been gathering momentum with the introduction of such processors by Intel and AMD. But you may be wondering which setup is more beneficial, multiple processors or a dual processor and what are the differences between them.

This article will attempt to answer your question. From the article:
