I am going to add that I would like to know the answer considering that I want a processor that will do more than 2 years from now before I need to change it again.

When I upgraded back in December, I got the top of the line from AMD, a good mobo and RAM for the price of a middling Intel chip.
According to this chart at PassMark, it's significantly faster.
Almost a thousand points higher.

well..price wise AMD will win no doubt about that and performance wise they're definitely not bad either. Intel chips r way over priced.
