So I've been looking at monitors and naturally I'm drawn to the "best rated" one which I found to be asus pg278q. Then I realized my evga 560ti wont be enough for the monitor. What graphics cards should I look at if I want to play on a 2560x1440 monitor? I'd be using it primarily for gaming but I'd love to leave options open if I ever wanted to start using it for something more intensive.
