I'v personally had good luck with AMD, and if you don't support amd then you might only have a single company to buy chips from in the future. But that being said you will not go wrong with the i7, which I am sure is surely better then what I have.

But i think for the price/performance mine is superior.

Not much difference in performance between these two but big difference in price .... Well 20 percent better performance for I7. the 920 I7 is $272 and the 6400 AMD is about $110
