What data are you basing this "20-25% gains" from?
1.) 4.8GHz on a 7700k vs 4GHz on a 1700(x) (+20%). Doable overclocks on both CPUs and single core performance is currently still king for gaming performance.
2.) CPU heavy gaming benchmarks like Watch Dogs 2 where a stock 7700k (4.5 GHz) is able to beat an overclocked 1700 (4 GHz) by 30%.

But you can also take a look at Witcher 3, GTA V etc. Maybe the average performance plus for the 7700k isn't exactly 20% on average, but it is still a better estimate than the 200% price premium nonsense.
Again: if you want a good PC for a low cost the r5 1600 is currently the best choice. If you need to handle gaming and heavy cpu workloads the 1700 is a very good choice. But if you only care about the best gaming performance the 7700k is the best choice out there.
But no, there is of course no reason to get intel over amd currently, because only AMD buyers are able to make educatated and reasonable decisions. Because everybody has the same needs when building a gaming PC.
