Coming from a GTX 970, I'd you should be fine. On less demanding games with my 970 I get 100-144FPS but on more demanding games like The Forest I get 60FPS on higher quality settings. If it gives you an idea, I was getting 100fps on 1080p and 60fps on 1440p. Maybe add 10fps to that? I got this monitor for my 970 and I think you will be very happy with 980 but if you want extra buttery smooth you may have to drop some settings. I've pretty much turned off AA
