Amazon offers the Intel Skylake Core i7-6700K 4GHz Quad-Core LGA 1151 Processor for $277.22 with free shipping. That's the best deal we could find by $2, although all other merchants charge $324 or more. (For further comparison, in February we saw it for $17 less, but only via in-store pickup.) It features a 2MB L2 cache and 8MB smart cache.
