Hi all, I should update my configuration for various reasons, creating a top/high end RIG, my main use is 4k Gaming (NOT competitive , I play everything) but I would also like a complete system at 360 ° that allow me to do everything without problems, especially a lot of multitasking even while gaming. At the moment in my country both the 8700K and the 7820X have the same price tag and the difference between the 2 platforms (including MOBO) is very little. I am evaluating the thing well and would like a tip from you guys :
My upgrade would be:
-i7 8700K.
-Gigabyte Aorus Gaming 7-Z370.
-32GB (4X8GB) 3866MHz CL16 GSkill Trident Z RGB.
-960 PRO (512GB) or Intel 900P 280GB.
OR :
--7-7820X.
--Gigabyte Aorus Gaming 7-X299.
--32GB (4X8GB) 3866MHz CL16 GSkill Trident Z RGB.
--960 PRO (512GB) or Intel 900P 280GB.
With both configurations I probably would do OC and Delid.
The rest of my configuration:
COOLER : Corsair H100i V.2 Push-Pull SP120 RGB.
STORAGE : HDD Western Digital Caviar Blue 1TB 7200RPM 64 CACHE + 960 EVO 1 TB
GPU: GTX 1080Ti Gigabyte Aorus Xtreme Edition .
AUDIO : DAC/AMP Schiit FULLA 2 .
Monitor: Samsung Curved KS7500 4K SUHD 43" .
PSU : EVGA SuperNova G2 850W (CABLEMOD E-SERIES ORANGE) + UPS Atlantis SineWave Professional .
Windows 10 PRO 64BIT .
Case: Corsair Crystal Series 570X RGB (6xSP120 RGB)+ PSU Cover MOD .
A huge thank you to all those who will help me in my choice. :)

The final answer will be: Intel Core i7-8700k.

The i7-8700k is the new king of high-end CPU's. it's great for multitasking, and ofcourse it's ideal for gaming. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k.
Where The I7-7820X is the second of three new Skylake-X HEDT (high end desktop processors) released by Intel as part of their core X series (the others being the flagship 10-core i9-7900X and the 6-core...

depending on how much do you need multi-tasking. If not much, 8700k is better due to its better single core performance. However, single 1080ti will be the bound for 4k gaming, two CPU will have similar gaming performance ~ 60FPS.

If you do heavy multi-tasking, Threadripper is better bang for the money and has better upgrade path. 3866 ram is overkill, 3200 should be more than enough, performance diff is little past that. 650W is more than enough for 8700k system.

The 7820X is an 8-core, 16-thread CPU which will amply satisfy all but the heaviest of multi-threaded use cases. The 7820X requires a relatively expensive X299 (Basin Falls) motherboard, which costs upwards of $250. The 7820X is listed at $599.

Money is something you must consider, the 8'th gen CPU+Motherboard COMBO will cost you aroud $600, where the i7-7820x+X299 combo costs around $700-800 on amazon USA.

So. finally it does make sense to go for a i7-8700k rather than i7-7820x, The i7-8700k will provide you more future-proof desktop, value for your money, and all the needs for multitasking and high-end gaming.

Thanks for reading my answer, hope it helps (sorry for my bad english)

Thanks a lot to both for the answer, based on that the CPUs and motherboards I could currently take them at the same price what would be the best choice? I will not do much multitasking, nothing heavy, also what are the advantages of the series X299 compared to a series "mainstream" like the Z370? For RAM, 3200 CL14/3600 CL 16 have the same price, the 3866 CL16 are at 40 euros more. Do you think between 3600 and 3866 are almost equal?

In that case, I will get 3600 unless you think 40 euros are nothing :)
X299 can have up to 18 cores 36 threads, but Z370 may only have 6 cores 12 threads. For heavy multitasking, you will need much more. However, X299 has less PCI lanes compared to AMD threadripper and much more expensive. X299 is close to an end as well, while X399 is relatively new. To me, either Z370 or X399 threadripper since you have the budget. If light multitasking, 8700k should satisfy your needs.

Thank you very much for the clarification, in the end I think it is more advisable to bet on Z370 or X399 as advice, the only fact is that for me the performance in gaming is very important and I have heard that the Threadripper of AMD go much less than Intel and they have pretty poor gaming performances you confirm? :)
