It depends entirely on the capacity you get, the 512GB 950 PRO is faster than the 512GB SM951. The 256GB SM951 will write faster than the 256GB 950 PRO, but the SM951 is an OEM product so you don't get a warranty from Samsung, only from the vendor you buy it from, which is usually a year warranty, whereas Samsung offer a 5 year warranty with the 950 PRO. Plus, the 950 PRO is a little cheaper for the 256GB model, and the 512GB variant is a fair bit cheaper.

As for the RAM, I agree that 32GB is OP, 16GB would be plenty in all honesty. There are several EVGA 980Ti's, and there's no need to go with EVGA over MSI. The cooler vendor doesn't really matter at all, and the "higher clock rate" means nothing, you can overclock your 980Ti anyway, and that MSI 980Ti with the AIO will out-perform any air cooled 980Ti, whether it's from EVGA or not. Also, EVGA cards do not have "more room for overclocking" at all. Buy whichever 980Ti you prefer the look of, and can afford.

What Intel 500 series SSDs? There are loads of 'em. The 520's are ridiculously expensive, and definitely not better than an 850-EVO. The only other 500 series SSD that seems to be in stock right now, is the 535 which is a little less expensive than the 850-EVO for a 480GB variant, but it's still not as good as the 850-EVO, plus the 850-EVO will last a lot longer.

Leave both 850-EVO's in if you want, or take out one of the 850-EVO's. Or, you could just get the 2 x 850-EVO's and not bother with the 950 PRO if you want, but the 950 PRO is significantly faster than the 850-EVO. You'll want the HDD for mass storage, especially for stuff like images, videos, etc, that don't belong on an SSD anyway. Use the 950 PRO as your boot drive, and for your favourite games/programs, then the 850-EVO as a spare SSD for when/if the 950 PRO runs out, that's how I'd do it personally.
