Do you mean 1440p or 144Hz? I'll assume 144Hz. First, that would be enough – gamers are flocking to those like crazy. Second, you have to really look at Multiplayer benchmarks here, not single player. In those Hyperthreading of the i7-7700K helps a lot when compared to the i5-7600K. If Ryzen can place a better model in between those two processor, that would be very nice.

144p (144 fields, progressive scan) as in 144Hz, in contrast to things like 60i (interlaced).

I know people love their 144Hz screens, but if you're generating 170FPS then the remainder is utterly wasted. You're "bottlenecking" the monitor.

So at some point you're spending money on stuff you don't need, the extra frames are simply thrown away.
