3.20GHz Intel Core i3
3.60GHz Intel Core i5

whats the difference between them. ones better then the other but which one and is it worth paying $200 extra for the 3.60GHx intel core i5 one?

I believe the i3 is a dual core, and the i5 is a quad core. It also has a higher clock speed, meaning your system will run faster. If you've got the money too - go for the i5.

They are both dual-core processors. The i5 has a higher clock speed and has turbo boost (which will increase the speed of the processor when required). If you aren't going to be running anything processor intensive, then the i3 will be fine.
