Similar to what I'm running, a 4690k with the hd 7850. It does ok on high at 1600x1200 usually between 50-60fps for crysis 2, far cry 3, cod ghosts etc, sometimes dips into the 40's on ultra. The gpu is definitely the weak link here, comparable to an r9 270 when oc'd a little. The 970 would be a nice boost. If your budget allowed I'd look into a better psu also, especially if you wanted to oc your cpu.
