Hey I know I'm a month late but just now had the chance to switch out my GPUs to test.
With 1080: https://www.userbenchmark.com/UserRun/21056522
With 970: https://www.userbenchmark.com/UserRun/21061147
I'm still super confused though because now with the same setup as before I had even purchased my 1080, my FPS is SIGNIFICANTLY lower than it was back then. (From almost always above 200 fps to barely hitting 120 with same components)
