You say you probably won't SLI, but the main reason to go x99 is for the extra PCIe lanes for SLI. So, you might consider going to a newer Skylake platform using an i7-6700K. The i7 only has 16 direct PCIe lanes, but given the speed of PCIe 3.0, you won't notice any change if you SLI 2 980 Ti in an x8/x8 configuration. The Z170 chipset has lots of extra PCie lanes for the SSD, etc.
Of course, if 6-cores is what you're after, than the x99 is currently the way to go, although you could consider some variant of a Xeon platform.
A 1000watt power supply is a bit overkill. Even 2x980 Ti in SLI would only need an 850watt power supply (and actually use much less than that). CPUs and GPUs are generally getting less power hungry, so future builds would probably require even less power.
I'd recommend a good 750watt power supply unless you are sure you are going to SLI 2 980 Tis in the near future. (If history repeats, there will be a single card in about 2 years that will work better than 2x980 and use less power.)
Unless you intend to seriously overclock the CPU, the 240mm cooler is also overkill. Since you intend to use this semi-professionally, I doubt you'll take the chance to drive an overclock to the glitchy edge. So, a basic 120mm AIO water cooler, or even a basic CM Hyper 212 is more than enough. If you don't intend to overclock, you can use the "stock" cooler or a CM Hyper TX3/TX4.
But, other than that, everything looks fine. I'm not sure (at this time) how the PCIe SSD affects the PCIe lanes in the x99 platform. The Z170 platform has enough PCIe lanes in the chipset to handle the SSD without affecting the lanes from the CPU.
Btw, while that Intel SSD is a great performer, etc, you might consider getting a motherboard with an M.2 slot and using one of the new Samsung NVMe M.2 drives, which are just as fast, but a bit cheaper.
