How about the new Core i7-3910K is based on the same Sandy Bridge-E C2-stepping silicon as the i7-3970X, and is said to feature 3.00 GHz clock speed. There's no clarity on exactly how many cores it features, but given that it's named in the i7-3900 series, and not the i7-3800 series, we're leaning toward it being a six-core part. A bid by Intel to clear out "imperfect" Sandy Bridge-E silicon by giving it a relatively low clock speed? We doubt that, it features the "K" brand extension, which denotes unlocked base-clock multiplier. Intel's cheapest LGA2011 six-core part is the i7-3930K, which goes for roughly US $550. If Intel prices this chip just right, by that we mean $400-ish, it could be a tease for all those shelling out $350 for a Core i7-4770K. Low clock speed, but unlocked. Two extra cores, quad-channel memory.
At around $400 only around $50 more then a 4770k, it looks like a great way to get on the socket 2011 X79 6 core overclocking bandwagon. If that CPU was around when I built my 2600k setup I would have been all over that CPU like a fiend. Also you could upgrade to a 6 or 8 core Ivy Bridge E CPU down the road and sell the 3910k to someone sporting a 4 core 3800 series CPU.
