Nope, no difference in performance.
I disagree. There is a difference in performance, although small. The K has higher base clock and is better binned. I don't know what currency OP is talking about, but the difference in price isn't worth the the performance gain unless they're going to be overclocking

So you're looking at $120 for the non K, and $170 for the K. I'd have a hard time recommending anyone spend that much on just a CPU that old, in either case. If you're using an i3 or i5 and really want that extra performance, and you can't wait and save up for a complete new cpu/ram/mobo, either one would be a step up. Don't spend the extra for the K though unless you're going to overclock. Also make sure your current cooler is sufficient to handle an I7, especially if you're going to be overclocking.

Now i have I5 3570K Stock

That's still a competent CPU, I don't think an I7 is the best use of funds in your situation, you're only looking at about a 20% increase in performance, in multithreaded applications. That i5 should hold you out until you can save up enough for a Ryzen system or something that will give you a much larger performance gain for not much more, especially in the used market.

Full AMD set is about 215€

Yeah, that should be plenty. Some AAA games you may have to turn down the graphics a little, but on eSports games like fortnite, Csgo, etc 60fps should be easy.
For the GTX 1070 is recommended I5-6500 and with I5 3570K they have very identical performance i read

There isn't any difference between those particular CPUs the OP mentioned.
There is differences in performance in some other K an non-K CPUs counterpart since their clock speeds differ.
There is just 100MHz difference with the same TDP and that doesn't even make a difference in benchmarks let alone in real world scenarios.
You might see a difference on the 6700 and 6700K for example, where the Non-K has 3.40 GHz stock with 4.0 GHz Turbo Frequency (65W) and the K 4.00 GHz stock Turbo Frequency 4.20 GHz (91W)
That will be a 600MHz and 26W higher and that will yield a bit of performance most seen on benchmarks.

While I am a fan of the 3770K and I got a long life from the 3770K in my main rig, I'd be hard-pressed to consider it worth the money to jump to a 3770/3770K when you already have a 3570K. Especially considering you have the ability to overclock your 3570K a bit as well. The money will be better used to save up towards a more significant platform update.

Words of wisdom.

Since you have Z77 mobo, you can go up high 4.1 ghz on all cores with the non K i7 3770. So the K doesn't really worth the extra money. I have gone far higher at 4.4 all core with my non K but i don't recommend it to anyone cause i ve tweaked base clock speeds and it took me large effort to make it stable.
I agree with the rest of the guys, better save up and go to a fresh platform.
