Based on Internet speculation, the range-topping parts will initially be available in two extreme hexa-core flavours; the top-of-the-line Core i7-3960X and the second-tier Core i7-3930K.
Both CPUs will be high on the Christmas shopping lists of many an enthusiast, but price tags of £850.79 and £477.59, respectively, suggest that you'd better start saving in earnest.
