Upgrade plan for future

[CPgamer1]

I've been thinking about ways I can upgrade my build in the future. Is it worth adding a second 1080 for SLI or should I just wait for a 1080 ti release and trade up to the ti then? Based off the rest of my build what are other parts I will want to look to upgrade or improve over time? My goal is to be able to run almost all games on Ultra at 1440p and 165fps. Only thing I can think of is overclocking my CPU to 4.6ghz if I need more power out of it.

I7-6700k @ 4.2ghz
NZXT Kraken 61i
ASUS TUF Sabertooth S
16GB RAM at 2400mhz
GTX 1080 FTW at 2000mz 5000mhz
Samsung 850 EVO 1TB and 500GB
EVGA Supernova 850w P2
NZXT H440 white

You're pretty well set up for now. As for future upgrades in next couple of years, who the heck knows, something better is going to show up by then. Might as well wait and see.
