Is that Firestrike score with a stock GPU?  As in no OC on the GPU?
What is the temp of your GPU while running the benchmark?
 
If your GPU is running anything over 60C, then you're losing anywhere from 26MHz - 39MHz or more depending on how high the temp gets.  It doesn't make much difference in gameplay, but on benchmark scores is where you'll see it.

So is 1949MHz the highest it boosts or is that where it settles to after the card heats up?
 
Your graphics score for a stock SC'd card in Firestrike looks about right.  Set up a custom fan curve using PrecX or MSI AB and get that temp down and you'll see a little increase in scores.  Look at my Firestrike score (in my sig).  That's with a pretty high OC on my GPU.  Both on the core and memory.
 
Also, a higher res (1440 or higher) monitor will typically perform better on these 1080 cards.

Any FPS you get over what your monitor is capable of isn't doing anything for how smooth it will be.  The idea of Gsync was/is for the display to show what your GPU can put out up to it's refresh rate and do it nice and smooth.  If you're not using Vsync or any other frame capping method, then try setting your game profile in the NVCPL to "Fast" in the Vsync section.  That may help.
 
My score is much higher compared to yours because my core clock was running between 2082 and 2095MHz.  It started out a bit above 2100 until I hit 55C then dropped a bit.  My memory was OC'd to a +250 if I recall.  I don't OC my GPU while gaming however.
 
Also, your score shows it better than 95% or other comparable setups...

I just noticed your system ram is showing you at 1333MHz in your Firestrike score.  Is that accurate?
 

It is. And every time i OC it over 1333mhz it endlessly restarts my PC. It's quad channel ram as well.
 
I also believe my ram is factory rated at 1866 MHz..
 
Even when I get 2000 MHz + on my overclocks my scores aren't that impressive on benchmarks :|

If you can't use the XMP profile for your ram due to instability, you could manually set it to 1600MHz and use the timings from the XMP profile.  Make sure to manually set your ram voltage as well to the mfg'r spec.
 
As far as your scores.  As I mentioned in a previous post, your FS scores are 95% better than comparable systems.  That is with no OC on your GPU.  Nothing to complain about there...

I overclocked my CPU to 4.4 GHz and stock GTx 1080 SC clocks.. Got DDR3 1666 MHz thanks to your guys' suggestions./ Processor still caps out at 60 Celsius even at this overclock (under max load). definitely seems to be able to be improved. I think my RAM's low clock may be slowing the PC down drastically. That 4427 is substantially better than what I've gotten before. Interestingly enough, HWMonitor shows 4000 MHz cap, but CPU-Z shows the accurate 4.4 GHz.\
 
 
EDIT: I got a clock_watchdog_timeout in games, so I upped my CPU vcore to 1.432 and my DRAM got upped as well. Seems stable now.
 
Running Prime95 and I'm getting 78 Celsius max CPU Core temperature at this voltage. EDIT, one spiked to 86 celsius.
 
Cancel that. WHEA_UNCORRECTABLE_ERROR when I hit 90 Celsius. Dropped VCore and DRAM slightly in an attempt to stabilize.

Looks good!  I'd say your GPU is performing well and once you get your CPU/Ram voltage dialed in and stable, you'll be all set...

FPS:110.8
Score:2791
Min FPS:29.2
Max FPS:222.4
 
 
 
 
Unigine Heaven. Check it out. I sat back and thought about what I really should be doing with my CPU's core and Memory. 4.4 GHz was simply unstable and I didn't care to spend a great deal of time adjusting. I dropped it down a hair to 4.3 GHz. In addition, I dropped the voltage two notches. As for the RAM, I was unable for the longest time to stabilize it and I was realizing that it may not be my CPU that was causing issues at all - it was just the RAM. Upped the RAM voltage 3 notches and stabilized it at 1636 MHz. The performance everywhere is a lot better than when it was at 1333 MHz. Not sure why, but it is. I think it's the stability.
 
Dropped the GPU clock back to stock superclocked levels which is around 1850 MHz, ran the benchmark and got those numbers. That seems a lot more realistic and more like the numbers I should be getting IMO, and I bet if I had a real pro here I could squeeze more out of my CPU and RAM. The GPU took 2050 MHz like it was nothing, but I noticed no real differences between the two anywhere. (Then again my benchmarks prior were before the PC was stable).
 
Do these numbers look better? Any other suggestions?


Thanks for all your help thus far.

Looks like you're good now. 

Yeah My card is still underperforming slightly and heating relatively high, but honestly it's not a noticeable difference in gameplay. I think I'll just swap out the rest of the system with a new chipset eventually and keep the GPU - that's causing more of hte slowdowns than the card IMO. Thanks for all your help Sajin and company.

have you tried sliding to bios position 2 and a reboot?

No what good would that do?

Yeah, should be around 135fps with a 1080GTX card on Heaven 4.0, that's on the high side with a +134mhz OC to core/+400mhz OC to memory and a 800mhz OC to my 4690k.
I think@ base clocks should hit about 110fps on a 1080.
 

Computer crashed at 4.5 GHz right away.
 
Anyway, went back down to 4.3, booted up Prime95 on blend and my PC froze and bluescreened immediately. Seems like a dying CPU to me. "Machine Check Exception". Perhaps that's the reason for my low performance?
 
EDIT: Running Small EFTs and the thing hasn't crashed yet. Now I'm leading to believe that there's a bad stick of RAM in there that's causing all of these problems in that case. Windows memory tester is useless.
 
Must say, I get stuttering frequently during playing. The only other time i had this happen was when I had faulty 4870 x2's back in the day with ATi. I don't know if it's really a fault GFX card, because the computer has been doing some strange things lately. For example, when I hold my mouse click down, it'll randomly release and click again on its own. Also icons on the desktop have been resetting randomly too. This just started happening a few days before I installed the GTX 1080. I wonder if it can actually just be the RAM..?
 
EDIT 2: Running Blend on Prime95 again and it hasn't crashed instantly. Must be randomly cycling through RAM to select?

4.3Ghz should be fine OC for that Cpu, if your crashing @ 4.5ghz just bump the Vcore a hair bit more. Remember its not voltage that ruins processors its degradation from over heating it.
Either way 4.3-4.4ghz should be fine for 1080GTX without a bottleneck.

Too much voltage will kill a processor...and degrade its life expectancy (that dang physics and electron migration!)
 
There is more to overclocking your processor than just setting a frequency, voltage, booting into Windows and calling it good.
 
When you overclock your CPU, you should do the following:
 
1. Memory at stock speeds
2. Get a stable CPU overclock
3. Overclock memory
 
My theory on CPU stability is to over test it.  The last thing I want to have happen is a BSOD...especially during a Windows update...that will bork your Windows and you have to reinstall.  I find the limit of my CPU overclock for a stable voltage, and then drop the frequency back by 100 or 200 MHz but keep the same voltage...to make me feel extra special.  Overkill...probably...but I haven't had any CPU stability issues in over a year...and my system runs 24/7.
 
Memory overclock doesn't buy you all that much in terms of performance.  It is an improvement, but you get the best bang for your buck by overclocking the CPU.
 
If you are having trouble overclocking your memory, it could be motherboard limited or CPU.  What works good as well is to decrease your RAM timings (many threads on the web about doing this).  You lock the memory frequency at where it's happy, and decrease the memory timings to get very close to the performance of higher clocked memory.
 
For my system (5820 K), I had difficulty overclocking my memory...it was rated to 3200 MHz, but I had issues with stability.  So, I brought the memory speed back to 2666 MHz, and decreased the timings by 20%...I got stability that way and very close to the same performance as a 3200 MHz memory clock.
