Seems to be a common occurrence with the 10XX series. My GTX 1080 SC constantly hits voltage and power limits, be it at stock or overclocked.
 
One thing you can try is to go into NVidia's control panel, manage 3D settings and switch the power mode to "Prefer maximum performance". With that turned on, the card will idle at stock speeds (1,749Mhz or something like that). The card tends to not hit voltage and power limits as often with that option turned on, though it does hit both eventually. The downside is that if you leave the setting on you'll constantly draw more power even while idling.
 
The thing is, even though it hits power and voltage limits, the clock always stays high. My card will only do +125 on the core clock and +500 on the memory clock. It will hit 2100Mhz while the temp is between 40 and 50 degrees, and then roll back to 2050 or 2088Mhz and stay there the rest of the time. I don't experience stuttering like you do though.
 
It's worth a shot, and if it doesn't fix the issue, you can always roll back the change in NVidia's control panel.

DabHandJonesNo matter what I change in PrecisionXOC, my power % is always hitting the roof and spiking a little over, also constantly causing my power Limit to ping pong. The negative of this being that the gpu is throttling back often and dropping frames , even just when using default settings.

Your power related graphs actually look pretty normal and don't explain the framerate drops you're describing.
 
A "1" in the power limit graph just means that at this point in time the power limit was reached, a "0" could mean anything between 0 and 99.99% power consumption. The "ping pong" curve you're describing is normal due to the nature how GPU boost and power limiting factors work. Going from 1 to 0 could e.g. mean your overall GPU power consumption just went from 100% to 99%.
As you can see in your graphs a power limit value of 1 doesn't mean that your GPU immediately drops the GPU clock and causes a noticeable framerate drop. Your GPU clock in fact looks quite stable around 2050 MHz.
 
Your "GPU usage %" graph however does show some anomalies and they indicate sth. different is wrong with your system. The GPU load dropping significantly below 100% could mean that sth. is throttling your system, like the CPU, RAM, heavy IO load/delays etc. If the GPU usage is going down the power consumption will of course go down as well, i.e. a drop in the GPU usage causes the power consumption to go down and it's usually not the other way round (at least not for drops by 20-40% which we see in your graph).
 
The Heaven benchmark you're using is far from being 100% efficient, i.e. framerate drops during scene changes or when textures / shaders have to be loaded are quite normal. Do you experience any framerate issues in actual games?

and yea 2050 is what you get when you 'K' boost yes? your voltage slider on the left panel in XOC should be at 100% if you not using 'K' and trying to OC
 
if your OC'ing to far then your going to have problems with the frame rate and heat and throttling which strangely enough your having, try running the PLAGame benchmark that was suggested to me by "bday"  rather than using heaven, if you still unhappy then take Sajin advice because it is sound advice, hope that helps?

use PLAGame benchmark or try running your bench again, if your using x99 mobo increase your System agent voltage to 0.350
 
always the way dude, have you got PhysX in the Nvidia control panel set to auto or one of the other settings?
 
contact Tek support, see how they would advise you on the matter, 
 
i don't know if you have looked at this thread by Sajin  have a look it makes a good read and it might be helpful to your situation,

Are you seeing the jumpy frame rates when just sitting still not moving in certain applications?

You mean outside of games? Just in windows on the browser and whatnot?

soz for butting in i wouldn't worry about it hitting power limit, hitting the pwr limit is good means the card is running at full volts i.e 1.094 on my 1080, dunno about 1070 but i assume it's the same top volts, what you find is that when the card warms up that voltage will drop if it drops to far that where you get your frame drop, if it doesn't drop it means you card and cooler is working well, if your finding that the volts are dropping to far then have a look to see if your card needs the thermal mod on the evga website, when i'm running benches and rottr or bf4 and most of my games the voltage limit stays at 1, my card and computer are dialed in spot on
 

SajinYes, to fix the power limit issue you will need to rma the card.
