Currently I am using a 1920x1080p monitor along with a gtx 660 ti, and I was recently thinking about upgrading to a gtx 970 or a gtx 980 for possibly wanting to upgrade to a 1440p monitor in the future. I am not sure if a single gtx 970 would be able to max games like the Witcher 3 (mostly maxed settings) and Batman Arkham Knight at the 1440p resolution, and that is why I was considering on possibly getting a gtx 980 instead. Would buying a single gtx 970 be enough, or should I spend the extra money and get a gtx 980 instead?
