There has been a driver update for the 900 series, you might want to update your drivers and see if that solves the issue. It also could have been a windows update, some windows updates give particularly poor results on some GPUs. If you can see if you can go back an update if that's what happened.

I should have mentioned I only built this machine 2 weeks ago and used the latest drivers which are still the most recent version. Windows updates are disabled and have been since install.

Did you go ahead and check thermals? It's possible it could be thermal throttling. But even at 40% usage you should be getting higher than 65 fps on wow. it was made over a decade ago. when was the last time you dusted the machine? If the GPU is doing well in the Benchmark ( whichever one you're using ) then I think we can rule out bad silicon. Keep in mind the 980ti was released in 2015 and is now 4 years old. Old hardware can go bad. As does everything! have you checked your drivers lately? That is the sort of thing that you wouldn't find on a 980ti but Even on my old R9 I was getting driver updates last year. 

You'd be better off using a coupler to run the coax cable to your bedroom, moving the router there and running ethernet off of that. Use an F type coupler to join the one in your basement to the one in your bedroom, then move the router. 
 
(All of you "RG-59 to RG-6 won't work" people get off my back it will work fine.) 

You should be able to move the router as long as you have coax at the new location. Just use a barrel connector to connect the current coax from the ONT to the coax running to the new room. 
 
Ill second that, I have RG59 from the outside going in to my basement. A new run of RG6 from the basement to the attic. And probably more RG59 from the attic to my room. I use this cable for internet and it works. 

I would verify that they are using the Coax from the ONT. It seems really odd that they would use coax unless you have TV. Usually the newer ONTs they use ethernet cable from the ONT with Coax just feeding the TV boxes.
 
If it is coax though, you can move your router anywhere with coax as long as it attached to the ONT.
