Rocking a 27" 1440p panel and even my GTX 660 can play basically all games at half decent settings at this resolution. I must say I'm getting a little exciting about what's coming this year. I might be given a reason to upgrade.
My friend is trying to get me into The Division. Loaded it up and 1080p @ high seems to work just fine (haven't seen a dip below 35fps) on my 7950 boost. The truth is, like my 2500k, I haven't felt a compelling need to upgrade my graphics card in 5 years; I only ended up with my 7950 because it was on such a good sale when the 3xx series was released. I suspect there are a lot of people out there thinking the exact same thing.
