I would not go any lower than a GTX 970 or an R9 390X for 1440p. However, a GTX 980Ti would be ideal.

I changed your build a bit. You don't really need the water cooling and all the fans. The 980Ti will run games much better at 1440p. The memory was overkill as Skylake memory doesn't scale well past 2666 mhz.

Go for Watercooling, the hassle it save you from cleaning dust is worth to have. Also remove some fan, go for classic one on bottom front and one in top back, it is work best that way.
Also your build is solid enough, if you have a love for the red camp and have the ca$h you can go for fury x for future proofing, if not go for little higher like neuronaut say R9 390X.

 

[Componentgirl90]

390x, 390, 970, 290x, 980, 980ti, fury x, 780ti

These are the types of cards that can handle it at the current time.

Firstly Merry Christmas to all

Happy Christmas.

Personally I wouldn't wait for a new processor. There seems to be little improvement in CPUs. Intel 2500k is nearly as good as the 4690k released I think 4 years later.
