1680x1050 - High Quality
At 1680x1050 the Radeon HD 6870 was the first graphics card to exceed an average frame rate of 60fps, though the 6850, GeForce GTX 560 Ti and GTX 650 Ti were close with over 50fps. The GeForce GTX 560 also did well averaging 47fps.
It's worth noting that while the GeForce GTX 560 managed 47fps in Black Ops II, at the same resolution in Modern Warfare 3 it was 60% faster, so this latest installment is clearly more demanding.
Having said that, it didnt take much to deliver playable performance at 1680x1050 and many will get away with mid-range graphics cards from previous generations.
