Like stated before, the card I bought is a used one, now to the meat of the problem.

I upgraded my GTX 670 with GTX 780 and tried playing Fortnite Battle Royale. To my surprise GTX 780 which is a superior card had a lot of FPS issues, it struggled to go above 50 in high-speed situations while my GTX 670 rarely dropped below 60 with same settings.

Not only is the FPS issue, but when I start FBR I get about 55-65 degrees Celsius heat and about 1900-2300 RPM fan speed on Hardware Monitor.

Is the card busted? I still haven't paid the guy I bought it from and I can return it if I know what's wrong with it.

I use i5-4690k CPU

EDIT:
Also my system shuts down in 10-20 minutes of playing Unreal Engine 4 games(Fortnite, Overwatch)

I guess the next thing is have you benched the card to see how it performs compared to its peers?

I'm not sure what the fan curves are supposed to be on any given model, you can always adjust them if you want to.

Also if you haven't done a complete reinstall of the graphics drivers, using either DDU, or Nvidia's option to do a clean install.

I didn't uninstall any drivers. GTX 670 and GTX 780 use the same drivers, I just swapped the card.

My GTX 780 also has really high RPM fan speeds. 2000 on 54C which makes my PC restart about 10 minutes into the game.
 


Uninstall and reinstall the drivers, trust us you just need to do this.

2000rpm is not making your PC restart, which is why I was noting that the temps are fine.

I did that, I got my FPS a little better, I think I can manage fixing that from this point myself.

Also RPM was 1200-1300 now instead of 1900-2300, so I guess that's better but my PC still shut off playing FortniteBR 10 minutes into the game. Do you think it's not getting enough power from PSU? I have both 4x4 pins connected.
