I'm planning to play at about 4x MSAA, from what I've seen in benchmarks, even at that anti-aliasing quality with highest settings turned on and playing at 4K, most games can hit about 50-70 fps. I'm talking about games like Crysis 3, which will hit 30fps with the above settings. However, I've also read that 30fps is fine for Crysis 3 as it's not very fast-paced.
