My new Motion-Design PC

[Jan Steffen]

I'm looking to build my new Motion-Design PC. The programs which I will use are Rendering with CPU (Cinema4D, Nuke...) and GPU (After Effects, Octane...).

 

CPU: Intel Core i7 6800K (LGA 2011-v3, 3.40GHz, Unlocked)

Graphics Card: 2x EVGA GTX 980 Ti Superclocked+ ACX 2.0+
Motherboard: ASUS X99-A II (LGA 2011-v3, Intel X99, ATX)
RAM: Corsair Vengeance LED (4x, 8GB, DDR4-3000) (Probably gonna upgrade to 8x8GB later?)

Storage 1: Samsung 950 Pro (256GB, M.2 2280)

Storage 2: Samsung 850 EVO Basic (1000GB, 2.5")

Power Supply: Corsair RM850x (850W)

CPU Cooler: Corsair Hydro Series H100i v2

Case: Corsair Carbide 400C

Operating System: Windows 10

So my questions for this build are:

1. Is this Motherboard a good choice and is the RAM compatible with it?
2. Is the Power Supply good, or would the RM750x be strong enough?
3. Is it better to buy 2x GTX 980 Ti (5632 CUDA Cores) or wait for the upcoming GTX 1080 Ti (3456 CUDA Cores)?
