Judging by the parts you have money burning a hole in your pocket!
If you have that much to burn, upgrade to an i7 XXXXK so you get the hyper threading, and a bigger SSD. I went with 128 and wish I had gone bigger. Also consider doing a custom water cooling loop for bonus points in looks!
If you want somthing more price to performance, down scale to a non-K processer (seriously, OCing does next to nothing for games anyways), drop the AIO cooler and go with an aftermarket air-cooler. Literally anything is better than stock. If you're dead set on the 1080 (I dont blame you) then great, otherwise a 1070 is going to be more than enough for the foreseeable future in terms of even the most demanding VR applications. Hell, a 1060 (when it comes) will likely be enough for a few years down the line.
Also look into people who are dropping used 900 series cards in your local area. If you can get a good deal on a 980 or even 980ti, that should be more than enough to power AAA games for the next few years.
