I'm building a three monitor setup, but I'm only going to be gaming on the middle screen. Will a gtx 760 2gb handle that and will a 750 watt psu be enough? I want to be able to game on one screen have skype open on the other and watch videos on the other screen. I play mostly league of legends, but I'm going to be going to be getting battlefield 4 when it comes out. I really want to have at least a steady 40 - 60 fps on both games.
Yes, for your needs, a gtx 760 and 750w psu will be fine. You probably won't be able to max everything for BF4, but you will at least be able to play comfortably on high settings with some ultra. For league you'll get anywhere from 150-300fps. Just cap it at 60fps if you want it to be stable
