I guess there is this caveat from the preview "Turbo mode was still stuck at a 1x increase over the stock frequency, so final Lynnfield performance should be much better in single and dual threaded apps than what you’ll see here today.", but I remain underwhelmed by how Intel is sitting on it's hands and just dribbling out such minor performance increases.

By the time this comes out, it will be close enough to 12 months since i7 was launched and we get F#$% all improvement.
