I have a five year old system with a GTX 960 card that has three DisplayPorts. I am getting three new monitors soon which will be 27" QHDs (2560x1440). Depending on which ones I go for they will have refresh rates of 60Hz, 75Hz and 170Hz respectively. My question is, if I go for one of the higher refresh rate models (ie the 75Hz or the 170Hz) will my graphics card be able to run them at this rate? I should add that this is NOT for gaming.
