Do you have any other GPU to rule out GPU issues? Spikes can be...
UPDATE 4
I did all the suggestions from
HOWIEJC troubleshooting guide, but it wasn't helpful in anyway.
I did the following actions:
UEFI:
- Install 1301 update and cleaned CMOS
- Customize fans curve and disable unnecessary EXT FANS
- Disable FastBoot
- Set X4 speed for PCIE3_3 and M.2_2 slots
- Set XMP 3,200 MHz
- Disable TurboBoost, SpeedShift/SpeedStep, C-states, Spread Spectrum and ASUS MultiCore Enhancement
- Set "Sync All Cores" to [37]
Windows:
- Completely reinstall Windows 7 and change to
Ultimate SP1 version
- Install all drivers
- Disable Windows Update, Defender and Firewall
- Set High Performance Mode
- Set Windows Timer Resolution to 0.5ms with TimerTool and did all tests with it been enabled in the tray
- Disable Core Parking & Frequency Scaling with ParkControl form BitSum
- Set almost ALL (except of Intel SMBUS A2A3) PCI devices to use MSI instead of traditional IRQ channels - Set mouse polling to 1,000 MHz
NVIDIA Control Panel:
- Set Max Pre-Rendered Frames to "1"
- Set Prefer Max Performance (even tried Optimal Power as you said in some of your posts)
- Set Threaded Optimization to "ON"
- Disable G-\VSync and AA
MSI Afterburner:
- Completely reinstall it
- Check and correct all AB settings to have the perfect config
Games:
- Do tests with MAXIMUM and MINIMUM possible graphics settings (TLDR: wasn't helpful)
- Change render quality
- Change screen resolution to MAX and MIN
Settings and games logs in Windows 7 Ultimate SP1 with no updates:

Can you help me with any working advice?
Because I'm completely disappointed about these issues on the TOP ~5K$ RIG. =(
I really want to know what is the culprit, software or what worse — hardware. And how I can figure out the source of all this c**p?
P.S.
1. Have you any similar issue on your PC? If yes, how are you get rid of issues on your rig? Do you removed stuttering completely?
2. What are the most valuable tweaks for your PC?
3. Do you notice issues after set UEFI and Windows settings to default?
4. Do you play and have any issues in PUBG, CS:GO or games that I've tested?
5. Does Steam (running in the tray) affect games performance?
6. Is it better to run games without Steam if possible or there are no noticeable changes?
P.S. 2
I'll retest games with 43 or 47 CPU multiplier and TurboBoost enabled.
