I'd personally go w/ the Z170 Chipset, due to the fact it shares alot of the same features of X99(Besides LGA2011/2011-V3 Processor support and up to 40 PCIe Lanes) and its cheaper;
Even If I had the money, I would still go w/ a Z170 Based system, due to the fact its the latest chipset from Intel, and like I said shares alot of the same features as X99
