Using 2400 ram? Even with OC you are missing out on about 20% performance vrs 3200.
And if you look at your own numbers, your 1600 comes in Gaming 66%, the 2600X Gaming is 94%. There's simply too much discrepancy to warrant claims of they are overpriced for the same thing.
They simply aren't. Pinnacle Ridge gets 7%-10% faster IPC. That's documented. It's the difference between Ivy-Bridge and Haswell, or Haswell Refresh and skylake, or kabylake and CoffeeLake.
And while IPC may or may not make any difference in games, is upto the game engine, in BF4 for instance, the old FX 8350 came in just behind the i7-4790k for fps, handily beating the i5-4690k simply due to better multi-thread use. Intels IPC put it on top. Anything like cs:go or skyrim, heavily single threaded optimized will rock with high IPC, but with Pinnacle Ridge IPC right behind CoffeeLake, there's honestly no real difference you could quantify. Max fps means nothing when above monitor refresh, only minimum fps counts there and either cpu line is well capable of over 144fps.
And just for 'it's and giggles, a stock Ryzen 1700 will win zip a file twice as fast as an i7-8700k. That's half as long, no matter what size file. Streaming? Ryzen beats Intel all day long. Intel currently has 1 advantage, just 1, higher IPC leading to higher max fps. By on average less than 20 fps. Big deal.
If you live for benchmark stats, fine, stick with Intel, you'll squeak out your Ryzen plus friends, but for all intents and purposes, when it comes to IRL gaming, they are equitable, same thing.
