Although it is best to purchase a computer that contains a Core 2 Duo factory installed in it, you can install it yourself. It is quite easy. You remove your computer's casing. Plug in the part. After you have installed the component, you simply install the drivers and software to your computer and it will work just as if it had been installed by professionals.
