GTX 1080 TI High GPU Usage, Low FPS

Hello. I actually RMA'ed the video card because I was absolutely clueless as to why this problem was happening but allow me to explain. I received a Zotac GTX 1080Ti AMP! Extreme and plugged it into my motherboard as usual. Plugged in the 2 8-pin connectors and booted the system. Everything worked fine initially. Then I went to try some games and tried Witcher 3 first. Initially, the performance was just as I expected, around 90-100 FPS at 99 gpu usage. This stays for about 4-5 minutes then, all of a sudden, the fps nearly halves itself to around the 50s, but the usage continues to stay at around 99-100. I try FFXV and the same thing happens.

I'm really dumbfounded because I have tried so many different solutions but none worked. I tried reinstalling several different drivers. DDU-ing before every installation. I have tried messing with the power options, setting them to high performance and whatnot. Making sure in the Nvidia control panel that high-performance graphics was selected. The GPU temperature was fine, staying at around 64ish degrees (although I noticed that when the FPS halves itself, the temperature begins to decrease, as well as the power usage in MSI Afterburner.) I even went as far as installing the card on my friends system and was met with the same results performance-wise (which is where I came to the conclusion that the card is faulty, but I want to have your guys' input on this which is why I am asking.) One difference I noted was that on my system, the RGB was working the entire time on the card and the fans never spun at idle whereas on my friends PC, I never managed to get the RGB to work but the fans were continuously spinning, even at idle. I also noted a small scratch on the top-middle part of the card which kinda indicates to me that it may have been mishandled? I want to believe that there is a power delivery issue taking place but on the side of the card.

In case anyone is wondering, CPU temps are fine too (roaming around 65c.)
I also read that some people who have had this issue have pointed out it could be some kinda of bitcoin miner malware that may be siphoning GPU usage but if that is the case, why do I not have this issue with my former GTX 1080 or GTX 770 or my friend's GTX 1070 on HIS PC. I also ran malwarebytes just to be sure and I didn't find anything. I'm one to normally blame the user for a hardware's fault but I've really run out of solutions on the users-side of this. As I said, I don't have that card anymore but does anyone have an idea as to what the culprit could have been? Just for my own curiosity's sake.

My PC specs:
CPU: i5-8600k @ 4.5 ghz
PSU: EVGA BQ 750w 80plus bronze
RAM: G. Skill Aegis 16gb @ 3000mhz
Mobo: MSI Z370 Gaming Plus
My former GPU was a Gigabyte GTX 1080

My friends specs:
CPU: i5-8600k @ 4.5 ghz
PSU: Corsair HX 750 80plus gold
RAM: G. Skill Aegis 8gb @ 3000mhz
Mobo: MSI Pro Carbon Z370
GPU: Asus GTX 1070

Like I said, both the systems suffered from the same problem with that 1080 ti but our other cards work fine. Is this the GPU?

That's a very strange phenomenon. I have a Zotac GTX 1080 AMP! Edition so I hope this helps:

From my personal experience, I've had nvidia drivers that seem to of lowered my FPS in specific games (ie titanfall 2) and lowered my temps of my card aswell (similar to what your experiencing but not NEARLY as bad.)

What I'd recommend is rolling back to an old driver, and see if your frame rate is bad. Next, if that doesn't work, try a different game and see if the FPS is bad there.

Well I don't have the card anymore as I RMA'd it but I just wanted to hear others' insight on the situation. But I did try about 3 different drivers and the issue persisted. I also tried 3 games at the time: Witcher 3, Final Fantasy 15, and Mafia 3. It happened in all of them but there was one instance where it worked for about 15-20 minutes in Final Fantasy as opposed to the usual 5ish before it started acting up. I know drivers can influence performance but I could literally be standing in the same spot in Witcher 3, running the game in 1440p at 90-100 fps and out of the no where, the FPS would half itself. Actually in Final Fantasy, there was a time where the performance dropped to the 20's (it halved itself from 95 to 50 and then again to the 20's) and the usage was still apparently 99%. A strange phenomenon indeed but my gut is telling me it's the card.

Well I just received my replacement card and everything is working as intended. Always saw getting a faulty card as a rarity but I guess there's a first for everything. Thanks for your response. :)
