This Ryzen build is my first with AMD since the Athlon days. If memory serves, Intel was still better for gaming at that time too but AMD was very affordable. I think the gap between AMD and Intel is even smaller now than it was back then.
AMD's don't require a manual overclock as the gains are minimal to none compared to letting the cpu auto-boost as designed. You do want fast memory 3600MHz-3800MHz with low latency.
So gaming performance, that all depends on your monitor resolution. I'm a 52 year old that has been into PC's since the Commodore 64 days.
The single biggest mistake I've made over the years is not investing in a really nice monitor. In your build you have a 2080Ti, do you have a 4k monitior? I would suggest a 2080 Super at most and use the savings on a IPS 1440p monitor if you're not looking for 4k.
I have had my Asus PG279Q for 6 months. The higher pixel count of 1440p has fantastic detail compared to 1080p and the colors of the IPS are simply...gorgeous! I'll never go back to 1080p or a TN panel.
Once you get into higher resolutions such as 1440p and up, the cpu is not the "bottleneck" as more demand is placed on the gpu. You will see the same FPS at 4k with a 9700k as you would with a 9900k. When you get to 1440p Intel leads by a few frames in some games and AMD leads in a few others. Just food for thought.
And finally, if you want Intel then the new 10,000 series provide better performance at a lower cost.
