What does a dual core processor do? and if i would have a 2.4Ghz dual core processor would i be able to run a game that requires 3.0Ghz?
i don't really understand the difference about a dual core and a single core processor plz help.

Sry for my english

Dual core processors are 2 processors running together.Think of a single pipe, this would be a single processor, everything goes through it.Now think of 2 pipes where all data is passed through 2 pipes so helping with the demands needed for modern games and applications.A 3 Mhz game should run on a dual 2.4 processor, I run fsx quite happily on a dual cor 2.4 processor.This link may help you http://www.wisegeek.com/what-i....
Hope this helps.

I just bought a dual core (2.0GHz pentium) laptop last week and it's fast!

I tend to have several programs all going at once, real resource hogs (html editor, image editor, email and browser all doing things at once, plus the firewall, virus/spyware scanner, a automatic website checker, etc, all sucking up resources).

I also added a lot of memory, but I think the dual core processor has made a big difference.

One of the biggest advantages of having a dual core processor is for the ability of the computer to perform thread level parallelism. A thread is a task that a computer puts resources to run.

For instance, if you have a computer running a Microsoft XP operating system, you can press ctrl - alt and the delete key and the task manager will come up. You can then click on the tab called processors, you will see a list of processes that the computer currently has assigned resources to. The higher the number to the right, the more intensive the computer processor is working on these tasks. These tasks are considered threads. With a dual or multi core processor, each individual core can work on tasks in parallel with each other. In common laments terms, you get much more performance from a dual or multi core processor.
