No surprises really. About 5-15% more CPU performance over a similarly priced Sandy Bridge. The GPU has bigger gains in the 30-40% range. You can finally play Skyrim at a decent frame rate now. Power usage wasn't quite as impressive as I was thinking, but it did go down a bit and that's a good direction.
