Intel Core i5-580M speeding toward a fall release at 2.66GHz?

The Core i5-540M is still quite rare on the ground, but we're hearing word that Intel is already prepping the assembly line for its successor. A new Core i5-580M has been dug up by the sleuths at Notebook Italia, who say it'll run at a default 2.66GHz and ramp up to 3.33GHz via Turbo Boost when needed. Those numbers compare favorably to the 2.53GHz and 3.06GHz of the 540M, and if Intel and company get their timing right,the 580M should be stealing some of that Core i7 thunder just in time for the back to school shopping rush. Won't hear any complaining from us if that turns out to be the case.
