The only way to future proof anything, is to freeze time. And somehow, I do not believe that you might have a time machine that can freeze time yet.
Now, on to the selections you made.
The I7-4790K is now 2 generations old. That is a Haswell CPU. Broadwell and Skylake CPU's have been released since that CPU was released. Broadwell only came out for the desktop in June, and Skylake is shipping, but hard to find at some places in the USA still. Intel says that problem should be resolved within 2 weeks.
So if you want the absolute latest, in an effort to try to be as futureproofed as you can be, you probably want to select an i7-6700K, which is the Skylake version of the i7-4790K. Be aware that it does not come with a CPU cooler, so you will need a new third party one, and the Z170 motherboard that it requires will most likely only be able to use DDR4 memory, not the older DDR3 memory. Some Z170 motherboards can use DDR3LP (low power) memory, but there is no benefit to using that if you do not already have DDR3LP memory, and almost nobody already has it.
I also notice that you made no mention at all of the most important item in your computer. The power supply. You need a high quality power supply in order for all of the other things inside of your case to function properly. I looked up that video card in a review Toms did on one, and in that case, it maxed out at 468.04 watts under a stress test. It was over 360 watts in games. So I am going to recommend at least a 650 watt power supply for you.
The power supplies listed below are top of the line power supplies. Two of these were actually cheaper than the 650 watt units, so I went ahead and selected these instead. All prices shown are from pcpartpicker.com, and may change at anytime, so click through to see what the current price(s) are.
