Looking forward to dumping Intel, but I don't think it's quite time. I am most definitely not a fan of Intel, but I certainly feel trapped. This is why...
An I5-8600K is $369 here. To surpass it's performance it appears we need a 1920X, and it still lags in gaming and desktop performance. Assuming the cpu.userbenchmark results of typical of the AMD CPU performance (http://cpu.userbenchmark.com/Compare/Intel-Core-i5-8600K-vs-AMD-Ryzen-TR-1920X/3941vs3934). So, if Australian Retailers passed on 100% of the price drop (Which would be highly unlikely - Aussie retailers love to gouge consumers)... Then there's no difference for the 1920x as AMD has not dropped the price of that CPU. So it's $369 vs $1,099. If we look at the 1800X which still falls behind the 8600K then we'd be looking at $369 vs $489 for the 1800X...
In most systems, games tend to be limited more by graphics card performance, and I'd be surprised if anyone could differentiate any performance difference between any of these current-generation, 4+core processors in typical desktop applications. And while Intel's current CPUs may offer a bit more performance per-core, allowing them to get slightly higher frame rates in moderately-threaded, CPU-limited scenarios, it doesn't matter much for anyone gaming on a 60Hz screen, since any of these processors should have no problem maintaining 60+fps in nearly all games. There can be a bit of a difference when using a 144Hz screen combined with a capable graphics card that can maintain frame rates in the 100+fps range, but at those frame rates the differences should be less noticeable anyway.
And comparing a processor like a 1920X with an 8600K for gaming is a bit silly. The 1920X is not really intended for gaming, and since today's games only make use of a handful of threads, most of the processor's 12 cores and 24 threads won't even be getting used. The reason to buy a Threadripper processor is for heavily multi-threaded applications like video encoding and 3D rendering, not for using a small portion of its cores for gaming on. As far as gaming is concerned, you could get a comparable level of performance by overclocking a $190 Ryzen 1600 on its stock cooler.
Also, UserBench can be great for doing quick, rough comparisons of the capabilities between pieces of hardware, but you can't just look at the "Effective Speed" percentage to compare processors with, and say that a Threadripper is similar in performance to an 8600K. They are very different processors, intended for different purposes. Scroll down a bit, and you'll see that much like the rest of the current Ryzen lineup, the 8600K outperforms the Threadripper CPUs in single and quad-core benchmarks, but the 1920X far outperforms it in heavily multithreaded tasks. The same goes for the Ryzen 1600, which is similarly outperformed in lightly threaded scenarios, but can pull ahead of the 8600K in applications that make full use of its 12 threads. You also have to keep in mind that the synthetic benchmarks used by UserBench for their comparisons can exaggerate performance differences, and the actual differences in gaming tend to be smaller.
I agree that the 8600K is a good processor when it comes to the majority of today's applications and games, and AMD currently doesn't have anything that quite matches its 144Hz gaming performance. Ultimately though, most gaming setups won't likely see a significant performance difference whether they have an 8600K, or a Ryzen 1600 that costs significantly less. Going by the suggested pricing listed here, it's possible to get a Ryzen 1600 with an AM4 motherboard starting at around USD $250, including a stock cooler that's capable of a decent amount of overclocking. By comparison, the 8600K with a motherboard and a lower-end tower cooler will set you back at least around $400. For a gaming system being built on a budget, that extra $150 could go toward the graphics card, which would make a large performance difference, compared to the minimal performance gains possible from going with the 8600K. Now, if someone is building a high-end system where cost isn't much of a concern, and they are getting a high refresh rate screen with a high-end graphics card to push those frame rates, then the 8600K or 8700K are probably reasonable choices. For most upper mid-range builds though, they demand too much of a price premium.
And of course, the second-generation Ryzen CPUs will be coming out in just a few months. I don't expect them to outperform the 8600K in games, but they will probably narrow the performance gap a bit more.

i will jump on the bandwagon when they will know how to cram 4 CPUs into 1 (64 threads), and that will be in the next 6 months hopefully.
They already have those, released last summer. What you describe are their 32 core, 64 thread Epyc CPUs for servers. It's even possible to install 2 of them together in certain motherboards for a total of 64 cores and 128 threads. Their prices start around a few thousand dollars each though, and they aren't intended for home use. Threadripper is pretty much just a pared down Epyc CPU with up to half its cores in place. There have been rumors that AMD is working on Epyc CPUs with double the cores and threads though, so maybe there will be a second generation Threadripper with more cores as well. Unless you have really specialized needs for heavily multithreaded performance though, even the existing Threadripper is probably excessive.
