Overclocking gpu vs. cpu in gaming.

[Vanswer]

From what I've read, there seems to be little benefit from overclocking your cpu in gaming, but I thought I'd ask the community specifically.

I'm able to get consistent +60 FPS on games like The Witcher 3, but I am noticing micro-stuttering and pop-ins that limit smooth gameplay and immersion respectively. At least, I think those are the words others are using to describe the same situation.

In a nutshell, would overclocking my FX 8320 cpu reduce micro-stutter and pop-ins? Same question for the GTX 970 gpu.

I've already changed a few things in NVIDIA's control panel: max pre-rendered frames=1, triple buffering on, adaptive v-sync, and max performance profile.

My specs:
CPU: AMD FX-8320
CPU Cooler: Coolermaster Hyper Evo 212
GPU: Gigabyte g1 Gaming GTX 970
MOBO: AsRock Fatal1ty 970
PSU: EVGA 600W 80+ Bronze
Storage: OCZ Arc 100 240BG SSD for Win 7 and games
Storage: WD 1TB 7200 HDD
Case: Corsair Carbide 200r
Case Fans: 2x120mm static pressure intakes (front and bottom), 1x120mm air flow exhaust (rear), 1x120mm airflow exhaust (top)
Optical: ASUS something or other

There is an advantage to over clocking both, gpus give you more fps gain per mhz added (clock and memory). The 8320 may give you 5-10 fps if you follow a guide on overclock.net.

I looked at a couple of guides and decided to start modestly and just increase the multiplier from 17.5 to 20.0 (4.0ghz). I ran Prime95 for about 20 minutes w/o issue. I know some say run it for x amount of hours but I went with this guide for the most part

Although there were no errors, I noticed in HWMonitor that the cpu clocks went down to 1.4ghz for a few seconds once the CPU package temp reached ~53-53C. Is this throttling? I was under the impression that only happened in the high 60s to 70s temps. Is there something in the BIOS that should be disabled/enabled?

I really think this post should be sticky one, and thanks again the tip with the AMD Overdrive really help me out with my speed and stability, now Im running 4.0ghz stable with even less voltage and a more cooler temperature.

It looks like my problem was that disabling AMD Turbo Core on bios does not work, you have to open AMD Overdrive and enable/disable it from there and then you will make the CPU reach its full speed all time, before the speed was throttling back to 3.4-3.6ghz, now I have 1.3v and 4.0ghz and its running very smoothly.

And thanks to this I have submited the case and call Asus service and tell them the problem with the bios so they can fix it on their next update (Hopefully)

Cheer!

before this turbo core tip i was getting 5.3 on cinebench at 4.0ghz or 4.2ghz, now Im getting 6.5 on cinebench and more stable and cooler cpu temp!
