Question about Intel Core i7-9700K

Short answer: NO.

- OC? 8700K (head/cooler)
- Gaming Comp/FHD? 8700K (HT/8 cores are almost not supported by any game anyway)
- Gaming 2K/4K? 8700K (GPU limit)
- Streaming? 8700K (HT) ...or then just the i9-9900K or Ryzen
- Rendering? 9700K (8C) ...or better Ryzen

So unless you're doing/gaming something really specific that benefits (immensely) from the 2 extra cores - don't.

Hello
My answer is 'rather no'!
Both the circumstance and the costs, and above all the benefits, are out of all reasonable proportion. The performance gain is hardly measurable, even in games. Stronger graphics, faster and more RAM and possibly also such hard disks are certainly more worthwhile. If you are a gamer, I recommend waiting for the next, even more powerful CPU generation and then possibly thinking about a new mainboard. If you are a 'normal' user, the question of power does not arise. If you have special, demanding applications, you should preferably look in the AMD camp, they are clearly ahead. Everything clear?

No the 8700k should be enough until the 12th gen of Intel comes out e.g. i7 12700K I would wait until it comes out because only from then on there will be any differences from the predecessor because from the 12th gen Intel will finally use 10nm maybe even 7nm but rather unlikely

Hello Simplyjens

I agree with the 2 previous answers, absolutely not.

The other 2 have already shown you that it is not worth it, I also have the 8700k and don't forget that you have 6/12 cores with the cpu and only 8 cores with the 9700.
The price is not worth it in any case, if you get an i9 9900k for the same price and already have a z390 board, then it's more likely.
