hi, i recently upgraded my gpu from 1050 ti to 1080 ti, but im experiencing bad performance. when i start up a game it runs very smooth (above 80 fps on ultra 1440p), but after a few minutes there is a sudden fps drop to arround 30fps, and it stays like that until i restart my pc, then it goes back to normal (drops again after few minutes of gaming) . temps are looking fine, gpu gets to 65 under load and cpu to 75 under load.
both cpu and gpu are not throttling.

specs:
cpu: i7 4770k 3.9ghz
gpu: Gigabyte GTX 1080 Ti Aorus Xtreme
motherboard: ASUS MAXIMUS VII RANGER
ram: 10gb DDR3-1333 / PC3-10600 DDR3 SDRAM UDIMM
power supply: corsair hx 1000i model: rps0004 (1000w)

things i have tried:
installing latest drivers after removing old ones with ddu
reinstalled windows (im using windows 10 btw)

would appreciate any help!

Your ram may be holding you back. And 10 gb? Try using 8gb only and see if this helps.
tried that, doesnt seem to do anything
could it be that my cpu is not good enough for the 1080 ti?
or because i dont have a ssd? or maybe the ddr3 1333mhz is too slow?

Why dont you use Afterburner to see whats wrong?
i do use msi afterburner, i have added a screenshot of afterburner stats before and after the sudden fps drop. cpu and gpu temps are fine, clocks never go down.
worth mentioning: after the sudden fps drop gpu usage jumped to 99%, and cpu usage and temps seemed to drop a little.
this is far cry new dawn played at 1440p ultra settings

I highly doubt your system is too weak for that card, there shouldn't be the slowdown you are getting.
I am getting better FPS on a 1070 with an i7-2600k than you do.

I'd try using DDU to remove all drivers and reinstall from new - how it says to do it using DDU

One thing I have done in the past to try and eliminate problems, is reinstall Windows on a different hard disk, which proves if it was a Software issue or not.
Its quite drastic but its a known cure of if it hardware or software problem.
To do this, remove your main drive, install windows on a different drive with a USB.

Again I would recommend selling your very slow 1333 memory and install 16gb of 2400mhz memory and spring for ssd for os/games/ This should cure all the slowness.

I don't agree with it being a RAM thing, just because it's only just started to happen.

One thing you can do, is sweep your computer for MALWARE and also limit all the things that start when the computer starts, but I still recommend a temporary install of windows 10 on another drive would rule out hardware.

Try chkdsk and defrag your HDD(check both disk options).Also in virtual memory set your main drive in "system managed".Also clear cache.Finally use crystaldiskinfo to check its health.

update: i've just got a call from the store i bought the card from, and they confirmed that it was indeed faulty, and they are sending me a new one (same 1080 ti model). the card should arrive in a few days and i'll update again when it does.
