Competition is a wonderful thing. If AMD hadn't launched its Phenom II X6 1090T Black Edition processor a little over a month ago, Intel probably wouldn't have retaliated by introducing the Core i7-875K last week. That would be a crying shame.
You see, the Core i7-875K, which is now available for $329.99 with free shipping at Newegg, isn't just Intel's cheapest quad-core processor with an unlocked upper multiplier. It's also a fantastic deal, with the same stock specifications as the old Core i7-870 for almost half the price. (The i7-870 still retails for $580.)
The Core i7-875K value proposition is so attractive that, at stock speed, it came out on top of both our performance-per-dollar and power-efficiency-per-dollar charts when we accounted for full system pricing. And when overclocked, well... let's just say we got ours from the base 2.93GHz to a staggering 4.13GHz, at which point it trailed the hexa-core Core i7-980X Extreme in Cinebench.
