100% FRESH build, win7 pro 64-bit, NVidia drivers downloaded directly from their site (NOT via Windows update/automatic install).
 
Bios: V2.02 & 8/29/2016 Chipset driver (most recent)
CPU: i7-6950X @ 4.2Ghz
Mobo: EVGA x99 FTW K
GPU: EVGA GTX 1080 FTW
Ram: GSkill F4-3200C14Q-GTZ
PSU: EVGA 1200P2
Case: EVGA DG-87
Cooler: Swiftech H320 X2 Prestige
 
Temps are fine, CPU is less than 45C while gaming, GPU temps remain below 68C while gaming with the core clock being in the 2000Mhz range.
The game runs smooth for about 5-10 minutes before I start getting insane packet loss & stuttering.

The yellow spikes are the packet loss, the graph given by BF4's internal network graphing.
 
I've tried repairing the game, the game is a FRESH install on a secondary HDD (had it this way for previous build and it worked fine with NO packet loss or issues). I'm using the Intel NIC on this motherboard and it's updated to the most recent drivers. I've tried turning "Optimize Network" "on" and "off" within BF4 itself with no luck. At first I thought it was just one server but the issue carries over to other ones too, ruling that out.

Cinebench: (top 3 are me, scores differ due to having background programs open when doing the test) https://puu.sh/rvAMg/522312b9b2.png
^Obviously no performance issues there.
 
Don't really know what else to do considering this issue never happened before to me. Every driver is current, FPS is 110+ on ultra at 1440p before this happens, temps are extremely low, yet I get stuttering which causes FPS to dip between 40-70, GPU usage spikes and has a sharp decrease (99% to 30% to 50%, etc. etc.)
 
Thanks for help in advance!
Note: IT'S ONLY WITH BATTLEFIELD 4.
 
 
UPDATE:
1.) Issue happens after a few minutes both in Multiplayer & Singleplayer.
2.) Rolling back Nvidia drivers did not solve the issue nor did re-installing current drivers while using DDU.
3.) Updated Router firmware & made sure my Intel NIC was up to date. No change.
4.) G-sync enabled/disabled. No change.
5.) CPU OC/base clocks. No change.
6.) GPU OC/base clocks. No change.
7.) Repaired the game. No change.
8.) Temperatures are well within reasonable limits.
 
I'm at a loss here for what to do.

I doubt it's overheating, but you can enable fan always and Disable Eco Mode.
You need to test voltage in idle and under full load.

How else can I do this feasibly?

Could be conflicting third party programs that use overlays (monitoring programs, in game features) or even a USB polling issue (what usb devices are connected to your computer and what mouse are you using?)
 
You are incredibly over powered for BF4, so normal issues with very high FPS and third party programs may be involved.. 
What screen res are you running and what is your monitor setup?
Its highly unlikely you have a PSU issue, software monitoring is never perfect and very often misleading... only a voltage meter should be trusted.
 
Make sure you have NOT installed the Geforce experience, if so reinstall the driver in custom mode and uncheck it. Reboot once after the driver install is complete -before- starting the game. This program is worse than useless for any 1080 user and should NEVER be installed.
--->Make SURE your NVCP is reset to -defaults- before starting testing, your 1080 has alot of unsupported features in BF4 and you will get the very best performance/quality using NVCP defaults and full Ultra settings in-game (with only max MSAA suggested at your performance levels depending on your monitor setup)
 
Next I would suggest turning OFF the in game monitoring feature, then close the game and then close Origin. Reboot, start origin, start game and verify its not running. While useful this feature should NOT be used when testing as it can CONFLICT with other programs that use overlays...
 
Next uninstall Precision completely and reboot the computer, we don't want precision running for our first testing pass.
 
Now test and you should be able to "tell" right away if the in game monitoring/Precision conflicts was the issue
 
You can put Precision back in for fan control and OC,s just dont use any overlays while playing, and you can always use the draw FPS command in game

GE3? You mean Geforce Experience?

In my opinion you really have 3 choices:  
#1 You could run with no Vsync at all in the NVCP or in game at matched refresh rates in the NVCP and in-game (my personal favorite) 
#2 Use the Nvidia G-sync feature with matched refresh rates in the NVCP and in-game
#3 Use "adaptive refresh" VSync in the NVCP and Vsync OFF in-game
 
Test with all 3 of the above and see what gives you the best experience

There are good chance that something with PSU is wrong because in same software with same PSU I have completely different reading.
It would be nice to connect voltmeter on molex black/red and black/yellow wire and check 12V and 5V rails under load or with PSU tester.

Your PSU is maybe for RMA.
I never hear that AIDA64 make such big mistakes with new PSU models, same is with HWInfo.
I was expect to see same with AIDA64.

Maniacvvv is probably the most knowledgeable person on the forums with BF4. Hopefully he can help you resolve this.

I hope so. It's like having a Lambo but you can only do half the speed limit.
