I've been trying a lot to address my issues, and in doing so found this site... hopefully you can help! First some basics.
Part List:
Core i7-6700K 4.0GHz Quad-Core, GeForce GTX 670 2GB, Level 10 GT Snow Edition ATX Full Tower - System Build - PCPartPicker
History of what has been done:
New build, several issues - possibly hardware, GPU, or windows apps : buildapc
A lot of the issues I've been troubleshooting so far have revolved around the NVidia driver - nvlddmkm. I am using onboard audio, and experiencing the pops in headphones and through speakers, both of which I've had for years with no issue. I took 3.5 minute snaps of watching youtube and playing a game (which definitely shows the nvlddmkm issue). One thing I noticed off the bat is that dxgkrnl.sys and storport.sys have the same ISR count, which seems odd.
One thing to note; there are times when I'm playing a game and am COMPLETELY bogged down... like 20 or lower FPS in games where I should have 140+, even with my rig performing poorly. That's when I experience tons of popping from the audio as well. If I alt+tab a handful of times, sometimes it appears that it will reset, my FPS will go back to somewhat normal, and I experience fewer pops. It's as if something failed and reset back to normal. Now, I do have TDR turned off, so the computer won't alert me/BSOD if the display driver crashes and recovers, so I'm guessing that's what happens.

If you have anything else you want me to try, whether it be a benchmark, changing settings, etc. or if there is any other information you need to know, I'm more than willing to provide it!

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:03:41 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:03:37 (h:mm:ss) on all processors.

_________________________________________________________________________________________________________
Computer name: TUNDRA
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: ASUSTeK COMPUTER INC., Z170-DELUXE
CPU: GenuineIntel Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz
Logical processors: 8
Processor groups: 1
RAM: 32683 MB total

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 4008 MHz
Measured CPU speed: 1 MHz (approx.)
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 7876.472064
Average measured interrupt to process latency (µs): 4.085144
Highest measured interrupt to DPC latency (µs): 7874.939130
Average measured interrupt to DPC latency (µs): 2.539468

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: chrome.exe
Total number of hard pagefaults 93
Hard pagefault count of hardest hit process: 71
Highest hard pagefault resolution time (µs): 2786.736277
Total time spent in hard pagefaults (%): 0.002599
Number of processes hit: 4
