There is an awful lot of wasted expense in that parts list, some of it would be better spent elsewhere such as on a better video card.
You do not need the aftermarket cooler and using it could void your 3yr CPU warranty should something go wrong with it.
You do not need and will not use 16GB of RAM with any present or due to be released game, 2 X 4GB sticks is adequate, you also have the option to add more in a couple of years should any new games then require it.
A 256GB is plenty for Windows and your favourite games, everything else should be stored on the 1TB HDD that you already have.
You need a better video card for the games that you want to play, the Asus GeForce GTX 1060 is only 192-bit when for Watchdog 2 to get the best video quality when gaming a 384-bit card is recommended, meet in the middle and go for a 256-bit card like the one that I suggested.
A very good choice of PSU but massive overkill and overspend for the intended build, again, stick with the PSU that I suggested.
To summarise, I would not use or suggest anyone else purchase anything on your list other than the CPU, MB and chassis.
