Old gpu died so I had to switchout a 1080 with a 3080 and paired it with my existing i7 6800

For the first month I didn't really notice it (although it could of happened) but lately i've noticed frame stutters and microfreezes (mostly just stutters though).
I've never experienced bottlenecking and i'm wondering if this is what i'm experiencing due to a older cpu being paired with a gpu.

I have capped my fps at 144hz and even on some older games like darksiders 2 I'd notice significant stutters. So i'm guessing that just because older games don't utilize as much gpu/cpu bottlenecking can still happen (if this truly is a bottle neck issue).
Some games that stutter don't get to 100% cpu usage and still causes stutters.
I checked to see if it's a faulty HHD/SSD (have games on both) and both have some games that work fine and some that stutter.

Can anyone give me any pointers and confirm if this is truly a bottle neck issue or should I do some benchmarks?
If it's bottlenecking I can at least just get a new MB and Cpu to resolve the issue.


Specs:
Cpu - Intel Core i7 6800K @ 3.40GHz
Ram - 32.0GB Unknown @ 1066MHz
MB - ASUSTeK COMPUTER INC. STRIX X99 GAMING
GPU - 4095MB NVIDIA GeForce RTX 3080 (ASUStek)
Storage: HHD + SSD (OS on SSD)

It is an older CPU, low boost speeds and low RAM speed. Even a 12100 would be an upgrade.

None of which matters. You've been looking in the wrong places mostly, because of a lack of understanding of what stuttering is.

Stuttering happens right at, or very close, to refresh, or more visibly when fps is double the refresh.

With a 60Hz monitor, the screen updates every 1/60 of a second, and either a new frame is available in time or it's not. If it's not, the display shows the same frame as the previous update, giving you 30fps, and if a new frame is ready you get 60fps. Micro stutter occurs when the frame rate fluctuates just enough that you might average 60fps, but some frames come a bit early and others come a bit late.

It's worst when the game is capped right at refresh since you effectively tell the gpu that it can never have a frame ready beforehand and waiting in the buffer, you can only have a frame ready every 1/60 of a second. Add 1 more object or detail that slows the frame time down even 0.0001 seconds, and it's too late, refresh cycle and you get 30fps.

If you disable vsync, that goes away, but now you run the risk of tearing, where frame time and refresh are out of sync and you get lines on the screen or moving objects cut in half and askew by a few pixels.

Try capping the fps at 200. Or for slower games 90/100 as that avoids running refresh/fps simultaneously. Make sure monitor v-sync is off but gpu v-sync/freesync is on

G sync was always on and i've capped at 143 fps.
Do faulty GPU's cause stutters?
