I always thought the i7 Hex were overpriced. DAMN intel!
Well, on the other hand of you buy one then you are pretty much set for life...
I mean even the "lowby" I7-3820 Sandy Bridge extreme still owns latest I7 Haswells and probably the same with Broadwell. It is still going to be relevant in the next 4-5 years easy.
Think about it - 1 CPU good for 7 years... That's a huge value.
