Just as the title says for upcoming next gen games like TitanFall, Watchdogs, Dayz Standalone mostly all next gen games on max settings before I have to upgrade?
Its hard to predict the future. Graphical improvements could stay the same for the next year or so, or someone could blow the door off the house. Hard to say. I would just get the 780 (Or 780TI).
The best i can get hopefully around 1080p Area, What about the 290X how long will that last the only thing putting me off it is I've heard it's hot/loud and has bad drivers?
