i was mucking about on mad max last night. my PC nails 1080p on full detail but at 4k its choppy.... i would not say unplayable but compared to a nice steady 60fps it is not great. i assumed because 1080p divides fairly nicely from 4k this would be the best resolution for my tv to not look odd, however on the off chance i gave 2560 x 1440 a go (QHD) I am so glad i did.... Visually you can barely tell it apart from 4k unless you swap between the 2, much better on my screen than 1080p and the performance on my gtx 980 is practically indistinguishable from 1080p - i have vsync on still as well so no tearing or anything. I will be trying this with all my games now. I have had this card now since November 2014, it was meant to be a short term interim upgrade for VR untill the gtx1080 came out, but to be honest it just keeps on delivering the goods. it has been a superb purchase for me. I will upgrade at some point in the turing generation, of that i am certain, however I will have fond memories of the maxwell generation..... and as an aside, I have now officially joined the QHD fanclub........ it bodes well for if even the next series of gpus cant quite manage 4k/60 on full bubble.
