[quotemsg=14436162,0,1793606]Not really , Ivy-Bridge E motherboards and memory are not that expansive. there is nothing new about the new Generation , just DDR4 which will make no difference in Quad channel anyways ... [/quotemsg]
The cheapest IB-E CPUs were still ~$100 more than the most expensive LGA1155 models and most motherboards were also $100-200 more than typical LGA1155 motherboards. That's a $200-300 premium for almost no extra performance over an i7-3770k. I would say that qualifies as an insane entry cost.
With Haswell-E, you get two extra cores even in the lowest-end model. Those used to cost yet another $200 extra on IB-E. This kind of offsets the $100-200 added cost of 16-32GB DDR4.
Basically, in either case, you end up paying about $500 extra to make LGA2011(-3) worth the trouble.
