Another great review Tom.
Well i think this generation is not worth upgrading to from few recent ones. Yea it is nice to have new processors often, but this feels like rebranding to me. High core speeds will benefit some apps, and games, but nothing ground braking. If you didn't upgrade for a while, yea this is a good buy, otherwise chill out, and w8 new architecture. Also this is Intel covering their blue butts just case AMD releases some high clock CPUs. This way they have 5GHz +, and they are safe.
