Is my GPU busted?

[Justforcause]

Hi. Please have a look at this video: https://streamable.com/k0nod You can see artifacts flashing.

My GPU is MSI GTX 1070 (close to 2 years old). It started happening today. In other games such as Overwatch I can see black squares flashing in the main menu, in Path of Exile I experience huge fps drops and stutters. I run games at 2560x1440 at 144hz if my PC allows. But the resolution is set to 1440p in all games.
Yesterday everything was fine in all of the above games.

Other pc specs:

Intel i5 6500
Kingston 16GB RAM
Samsung SSD 250GB HDD
MSI Night Elf B150M

I have tried reinstalling drivers, updating to the newest ones, even older drivers. I tried switching display cables from DP to DVI. All of this nothing.

I tried different GPU GT 640 (suuuuper old) and here I did not get the artifacts. And all fo the above games were fine without the issues.

Is my GPU done?
Can it be the power cables to the GPU? As they have been rather squeezed between the side cover and the GPU , there is not enough space so there were bend.

I can still claim warranty within 2 years time period.

Is your video RAM/GPU overclocked? If so, turn it down to stock and see what happens. If it's running stock your card is exhibiting classic failure artifacts that are most likely from the video cards memory.

However, I've seen this sometimes from a card overheating so you need to check your temps when gaming. Make sure the fans are running and not clogged up.

NM, dupe post.​

Looks like it's toast, yeah.

DooKey: U run at stock. I was checking my temperatures and while gaming in super demanding games my temps were as high as 81-83 max in high intense moments. Other HW temperatures (CPU, SSD etc.) were completely normal. I assume these temperatures are fine right? My fans are spinning and there is no dust clogging them. Then I have to RMA it, correct?

Thnak you a lot for your answer.

Yep, time to RMA.

Is there a way to tell what caused it? Just the GPU itself went bad? Or something else caused it like bad PSU?

Nah, sometimes they just go bad. Electronics are like that. I've had a couple of GPU's die that way after a couple of years use.
