Hi friends,
  I am thinking about getting laptop for my brother back home and trying to decide among various choices.

 I was jus curious how do all these processors compare to each other given there are literally so many choices among those Intel and AMD chips like i3,i5,i7,phenom,athlon and all those....which 1s are equivalent or which 1 is better among them,,

Can some1 provide some insight on this.. I am really curious..how do they compare..even though I am sure it's all marketting.
