Amdlova :
Amd as good CPU but in a Small ITX it will fry an egg. A Good old 7790 (260x) can handle the games 1920x1080 fine. My last graphic card is a 670 with Nvidia cooler and it added a lot of temps on my micro building pch about 80ºc and cpu get 10ºc more. its desing blower type but the heat its all around the card. I got here the noctua cp-12se14 stock i5 3470 (105fsb) and 37 locked multiplier about 4.0ghz stock voltage. ITXand m-atx build with high TDP can be a mess.

The 860K is not well suited for ITX builds. Too hot for such a confined build IMO. It's best in a microATX or larger budget build. Something around $500-600, with space for a decent budget tower cooler, that's about the only time it makes sense. It's also a lot easier to produce better overclocking results with a larger board/tower/cooler. When you're competing against a more expensive processor and yet your final price tag is higher, "you done fudged up, son".
Oh and don't trust ANY reported temps with an 860K (or probably any Kaveri). They're all garbage results. ALL of them, even BIOS numbers are shady as heck. You can however use AMD's Overdrive software and it will give you decently reliable thermal HEADROOM numbers, not temps. But the thermal headroom is all you really need to know where you stand, overclocking-wise.
I actually have to disagree with both of you about these FM2(+) cpu's/apu not well suit for an ITX system. They're very capable in such system.
Me and a few other people in this very comment section have already mentioned about having a ITX FM2+ system that are doing quiet well with them and i have to say that My A10-7850k probably runs a lot hotter than a AMD Athlon 860k because of that IGPU...
Unlike a ATX build and possibly a mATX (depending on the case), you just cant throw random hardware into an ITX case and expect not to have problems.
Now im not using the world smallest ITX case with the silverstone RVZ01... but being a slim console like case, my cpu coolers choices are extremely limited to 83mm in hight. Thats doesn't leave you with a lot of options... Heck even are some AIO coolers you cant fit into this thing....
That's is certainly way more limiting than this thermaltake case.... but yet, I have really pretty cool temps depending on what voltage/GHz im wanting to run at with the Coolermaster Geminii M4.
Thermal magins dont typically drop below 45C when under full load @3.7GHz and 1.2v. and if i overclock to 4.4GHz with 1.38v, i wont drop below 25c normally under full load (unless it's a really hot day).
and my temps have slightly improved when disabling my IGPU with adding a GPU card (GTX 980ti mainly for folding@home).
Now am I saying that an intel system cant be better in this space? of course not.
Those little buggers can stay really cool and use so little power... It's no contest. Although saying that an AMD system is not
suited for ITX is misleading...
Although if you really want something that's is not suited for ITX system but asrock manage to make it happen anyways...
Maybe you should be looking at the ITX X99 systems.... For processors that have a TDP about 50% more than a 860k/7850k, those under full load kick out way more heat than even my 7850k cpu and igpu running @100%.
PCpartpicker has a few of them and lets just say they're running cool thanks to at least some kind of planing.
