SORRY I HAVE TO WRITE EN INGLISH

I want to get new laptop. But I’m concerned about the kind of the processor. There are two laptops I liked having almost same specifications but the processor is different. One has Intel® Core™ Duo Processor 2.0 GHz and another has Intel® Core 2 ™ Duo Processor 1.8 GHz.

Can you help me in the decision process and tell me which one can give me higher performance?

Thank you
