Is your cpu overclocked? You could try to mess with vsr or with the build in resolution scaler to see if it helps

Wooohah
I don't have it overclocked yet so stock 3.5ghz and 3.9ghz boost.

Whats VSR?

I tried turning AA to high and resolution scale to 110, but that just increased GPU and CPU load, didn't bring down CPU load.

Well, you're only running at 1080p so you're more or less CPU limited until you increase the load on your GPU.  Over clocking will help somewhat. Games are becoming more multi-threaded. I'm not sure how much only having 4 threads is limiting you.

Is overclocking really the only solution?

I'm upgrading to 2k very soon, its just a matter of finding a monitor at this point. I'm thinking 2k at like 75hz or something like that.

That should increase load on my GPU and take some load off my CPU right? or will I still need to OC then?

totally different situation here, running also 6600K and 1070FTW (no OC on both).
while playing BF1 my GPU is almost constantly at %100, driver is the 376.19 whql.
never had so much fluctuation on the GPU usage like you do.
I think if there is a reason for it it's most likely not the cpu (assuming there is no heat issue of any kind).
 
my temps are below 45C for CPU and around 55C for GPU, under full game load.

if I disable HT on my 4770k at 4.3 then I see plenty of games fully pegging the cpu. the first Watch Dogs will hitch and stutter with HT off and even Mafia 3 loses about 25% peromance and feels like garbage just trying to pan around with HT off. I just laugh at the people that think we dont need more than 4 cores even on high end gaming pc. these would be the same clowns that say you dont ever need more than 8gb of system ram and that memory speed does not ever matter either. 

A 6600K is not going to bottleneck a 1070. My 4690K didn't bottleneck my 1070. What exactly are your frame rates? Compare it to others with the 1070 and if it's the same or close who cares.

Wooohah
Whats HT? I'm not fully understanding your comment lol

I mean I have an i5, before buying the 1070 everyone assured me my i5 wouldnt bottleneck it and I would be fine. More or less the same thing is even happening with BF4 lol. 

And I've got Trident Z, 16GB at 3200mhz

He is saying he turned his Hyper Threading off on his i7 6700K which turns it into your i5 6600K. And that is what he discovered. You would probably be best served with getting an i7 or waiting a bit for the new Intel i7 to launch. They will be compatible with the current Z170 boards with a BIOS update.
 
People need to get out of the dark ages and stop recommending the i5.

No difference, overclock, get something out of your current CPU. The 7700K will only be compatible with Z170 through a BIOS update if one is supplied. Otherwise, you will need to get a Z270 Board.

I got my i5 6600k overclocked to 4.4 GHz and also have it as a bottleneck in Battlefield 1 on 100%

1080p is the problem. Running a higher resolution/overclocking the cpu should help. Use DSR inside the nvidia control panel to increase your resolution, use the first resolution that allows your gpu to work at 100% usage.

1080P is too easy on the GPU and it will keep hitting the CPU with "now what" because those 10 series GPUs are that good.
 
If yo do not have the stock CPU cooler, OC the CPU is easy enough to do.
 
As long as you do not need hyper-threading for your software, the I5 is a good CPU
(edit typo)

Battlefield is pretty CPU bound because of the high number of players in a match. An i5 6600K could be a slight bottleneck for a 1070.
If you want more frames at 1080p then oc that cpu.

Battlefield 1 eats up the CPU.  My 3960X at 3.8ghz gets hit 100% in that game also.  It must be hitting the CPU hard since my fans on my radiator really ramp up on that game.

My Firestrike scores show my i7-4790k is better at driving my video boards than this i7-6700k both at 4.6 GHz. The 6700k gives me slightly higher PhysX scores but the 4790k gives me better graphics scores across the board. As soon as I have time I am going back to my 4790k and putting this 6700k and the ASUS rubbish on a shelf somewhere convenient so I can forget it exists.

Hey there,
 
The problem, like Sajin said, is your current monitor resolution (1080p). Most games are just starting to tap out the Core i5/i7 series back from 2011 (Sandy Bridge), so a current Skylake or previous Broadwell and Ivy Bridge i5 processors offer more than enough horsepower to feed a 1070 or a 1080.
 
I'm running an i5 6600K, and even at stock speeds processor usage doesn't go above 60 to 70 percent, depending on the game. Even multithreaded games don't tax an i5 6600K enough, because most multithreaded games aren't really that well optimized to take full advantage of an i5's four cores, much less the eight cores on an i7. There is no need for you to upgrade to an i7 with the current generation of games (or even most games coming down the pipeline) in order to take full advantage of a 1070. Most games will be GPU-bound before they are close to being CPU-bound.
 
The difference is that I use a GTX 1080 to run a 1440p 27 inch monitor (ASUS PB278Q). In my scenario, GPU usage (depending on game) stays between 90 and 100 percent; as an example, Titanfall 2 takes the 1080 regularly to 90 percent, while the i5 workload fluctuates between 40 and 60 percent. Framerates with every graphical setting on max yields, on average, 98 to 130 FPS with VSync off.
 
You do not need an i7 to keep a 1070/1080 fed, you just need to game at a higher resolution. An i7 is great if you use multithreaded workloads like video/sound editing, 3D content creation/modelling, but for pure gaming an i5 is more than enough. At 1080p, a 1070/1080 will keep its clock at 1.5Ghz or a bit lower because it doesn't need it's full speed to render over 100 FPS.
 
My i5 6600K will accept a max, stable overclock of 4.7Ghz at 1.355 volts. The FPS gain at that speed is negligible, at best. Plus, going up to an i7 would introduce more heat into the system.
 
You'll hear people say an i5 is not enough and to go with an i7, but I can tell you from experience that it doesn't matter. Save your money, keep the i5 and invest in a good 1440p monitor.
