PC Stutters in All Games. NOT AN HDD ISSUE. CPU or GPU?

Hello again. My PC has sever stuttering and texture pop-in issues in all games, including Minecraft. I tested my RAM sticks induvidually (They're fine) and the issue still persists.

I then went on to test my HDD and SSD and the issue happens on both. It even occurred on a virtual RAM drive that had 10GB/s speed!

I think I've narrowed down the problem to the CPU or GPU, and I need your help to find out which it is. Here goes something...

I've had a history of overclocking my GPU, and the results were fine, until I began artifacting in some areas, even after removing the OC, but no stutter, and I haven't seen any artifacts in a while. I don't think my CPU ever overheated since its water-cooled and never really goes above 80 degrees. HOWEVER, this stuttering issue arose about 4 months ago when I was running the piss out of Dolphin Emulator, a VERY CPU-intensive application, if that has anything to do with it.

Here's the problem, though. I ran lots of benchmarks and BOTH my CPU and GPU score normally for their models, not even a little below average. So, what can I do to weed out the culprit once and for all?

PC Specs:
HDD: WD Velociraptor 500GB (10,000 RPM)
SSD: SanDisk 120GB SSD
GPU: AMD Radeon R9 290X 4GB
CPU: Intel Core i7 4930K @3.7GHz
RAM: 32GB ADATA XPG V2.0 (1866MHz)
MoBo: Gigabyte GA X79-UP4 (Custom CPU water cooler)

Yeah just a point of reference, by overclocking you're pushing a gpu past what it's intended to do. If you did something like overvolt the card when overclocking or something else, you could've permanently damaged. Don't overclock until you've done extensive testing. If you have a friends gpu plug it in if the artificating persists you can narrow it down to the motherboard or cpu. Your cpu reached 80 degrees? thats bad pretty bad. For how long, it could definetley be some damage to the cpu, only if you left it on at those degrees for a long time. Cpu's shouldn't hit those kinds of temperatures if that was the gpu that would've been fine but cpu's don't have that high of a thermal threshold.

I'd recomend undervolting the cpu immediately. Maybe even dropping the clock until the temps are peaking at around 66 degrees. Thats the recomended thermal ceiling for that card from intel. Anything above that you risk permanent damage and shortening the life of the cpu. Maybe 70c maximum.

The CPU only hit 75 degrees when running Prime95 for about an hour. It NEVER gets even into the 60s under normal use or heavy gaming. It's not overclocked or overvolted. I'm hoping that the problem IS a damaged GPU or bad GPU memory, but it scores ver 10,000 in FireStrike, so how could it be bad? I have an older GPU I could test to see if stuttering persists. Should I do that?

Yes, trying another graphics card will rule out that the GPU is faulty. Have you done a memory test by the way?

If it's hitting 75's in prime 95 you're fine, prime 95 isn't exactly a real life scenario of what temps the cpu can reach, you're fine cpu wise, so it's most likely the gpu, like i said, if you have a second gpu you can plug in or a friends you can borrow just to rule out the gpu's fi their's still artifacts with a different gpu it could be the motherboard and or cpu. But if its stable at 60c's under load nothing to worry about.

The only thing that jumps (VERY LITTLE) is CPU usage when it stutters, but the CPU scores fine in benchmarks and this happens on both HDD and SSD. Also, I don't think a damaged CPU would only cause video related issues like texture pop in and stuttering. If the CPU was damaged, we're looking at possible system failure or black-screens during games. HDD usage is normal.
