Good for him but I've seen a Core i5 reach 5GHz using an unlocked version on air.
I'm mainly against Sandy Bridge for now because it'll cost a lot to get a version that will overclock. I just want to buy a processor and increase it's clock speed to get the performance I need.
I think AMD will be gaining a traction of the overclocking business since, well they haven't done what Intel has done yet.
Core i5 does OC well.
OC'ing without destroying the equipment is gonna be the key though.
That screenshot on the front page is at the default OEM! What you really want to see is this one!:
