Hi, Kamal.  Thanks for the great question.

I think that the question these days isn’t really “single core or dual core”, but “dual core or quad core.”  I recently upgraded my cell phone from a single core Samsung Captivate to a dual-core Sony Xperia Ion, and let me tell you… the speed difference on Angry Birds is amazing.

So this question… like so many where computers are concerned… is “What will you be using your computer for?”  If you basically use your e-mail for banking, chat, homework, maybe the occasional YouTube video, then a single-core processor is fine.  And you can get them at bargain-basement prices (if you can find them) because retailers are trying to get rid of them.  If you’re a casual gamer, like to stream HD Netflix movies, then you’ll probably want to go with a dual-core processor.  If you’re a hardcore gamer or you edit HD movies and don’t want to wait a week for them to render, or you run architectural software or something like that, you might think about breaking down and getting a quad-core processor.  

Here’s a way to think of the difference in speeds.  Have you ever been at the bank or the theater with a long line and only one cashier or teller open?   Things drag merrily along at a snail’s pace as you creep toward your destination.  Then suddenly, miraculously, they open a second window.  How much does that speed the line up?  Then, they open a third and fourth window, which allows them to break the existing line in two, and process two people at a time from each of the lines.  NOW how fast does the line move?

AMD tried introducing a tri-core processor for a while, but benchmark testing proved it to be not appreciably faster than the dual-core.  The reason?  It was still feeding from one line of data.  With an odd number of cores, you lose the ability to sub-divide the line of data.

I hope that this helps.
