I am building a Gaming PC for the first time and almost done choosing my components but just stuck between two graphics cards the AMD R9 290x and the GTX 780 over clocked with ACX cooler both are linked below. I'm looking to be able to play next gen games on max setting at about 60-80 FPS, both are similar prices so don't include pricing in this please. Thank you in advance.
