Will this run games maxed on 1440p?



Both these benchmarking reviews disagree with you:

The links you posted are showing max or average FPS...not the minimum. All games will fluctuate depending on whats happening on screen at any given time during game play. The 970 will not hold above 60fps all the time...it would likely take a GTX 980 or AMD 290X to keep the minimum above 60 fps at all times.
 


They show average, which is all you can really count on. Even a 980 or a 290X cannot support the minimum above 60 fps at ALL times. http://hexus.net/tech/reviews/graphics/78157-evga-geforce-gtx-980-classified/?page=5
 

I hope that you understand what a stable FPS means, right? Meaning it will not drop under 60 at any time.
 


For the most part, stable and average mean the same. Stable is more of a range, but is heavily based on the average. Saying something will never go under 60 fps when it has a minimum lower than 60 is just wrong. I hope you can see benchmarks.
