[SOLVED] My PC is bottlenecked and I'd like to buy a new CPU

[itachi the homie]

Hey guys,
I recently got my hands on a 3070 so I thought now is a good time to upgrade my PC. My specs currently are the following:

Asus Prime Z270-P (LGA 1151)
RTX 3070
i5-7600K
16GB RAM
700W PSU

Well, as you can notice my build is bottlenecked pretty badly, my other GPU (GTX 1060) fits way better into this system, but I'd like to upgrade so I can play all my games in peace. Any recommendations on what to get, I've looked at a couple of alternatives but the i7-9700K would be pretty expensive, maybe an option that's like 50-100€ less (i5-9600K maybe)?

Thanks in advance

I'm sorry if this post is in the wrong category

The best you can get is an i7-7700K. You have to buy a new motherboard if you want to get something better.

Oh, I see. I thought you can use 1151 v2 with the older boards as well.
