Z170 i7 6700k vs Broadwell E

[Ticonderoga]

I was wondering if any of you had some input regarding
Z170 i7 6700k vs Broadwell E setup?
I had settled for a I7 6700K but it turned out to be faulty so I had to send it back.
But now I am contemplating waiting for a Broadwell E hexacore instead. I understand it is supposed to be realease Q2 2016?
Currently I can get the MSI X99S Xpower AC mobo for less money than the mid tier z170 boards where I live. (special deal due to stock clearance)

Anyway it would all boils down to the following setups :

I7 6700k cpu
Asus Viii Ranger Z170 mobo
Evga supernova g2 750 w
DDR 4 Corsair Vengeance LPX black 3000 mhz
Samsung EVO 850 SSD


Or

Broadwell E Cpu
MSI X99S Xpower AC mobo
Evga supernova g2 750 w
DDR 4 Corsair Vengeance LPX black 3000 mhz
Samsung EVO 850 SSD

I ended up getting the x99 mobo and a secondhand I7 5930K.
Been using it for about a week now and it is brilliant.
The mobo wasn't too expensive and the 5930k cost me about the same as a new 6700k costs and it still has 2 years of warranty left
