you know thats the thing it is better to pay a little bit more and few years later dont worry about changing your cpu beacuse fps drops or some shit. besides that yeah price is also a thing there. i would rather pick 9900k than 9700k actually
In some benchmarks 3900x might beat 9900k/9700k by a small margin and in some benchmarks its intel that clearly wins.
The fact thought is that there is no ryzen available that has better Single core performance than 9700k at 5ghz. My friend has shitty 3600x and I score +120fps more than him on FPS benchmark with the same video settings and same ram.
Also, userbenchmark proves my point when comparing 9700k to any Ryzen, there is just no competition in benchmarks made by regular PC users.
