Been hanging around forums for years but I still feel like such a beginner when I dive into the actual BIOS settings lol. Honestly, I learned the hard way with my current setup that you dont always need to buy the most expensive flagship board to get a solid result. I spent way too much on the one I got, thinking I needed it for my i9, but I realized later I could've saved like $200 and still hit my targets. Basically, I started checking out VRM tier lists on sites like TechPowerUp and watching deep-dive videos on YouTube from guys like Buildzoid (Actually Hardcore Overclocking). It really opened my eyes to where the diminishing returns hit. Are you planning on doing sub-zero cooling or just normal daily use? Because if its just daily, some of those mid-tier boards are beasts for way less money. (At least thats what worked for me) TL;DR: Don't get distracted by the flashy marketing. Use resources like HWBot or VRM thermal spreadsheets to find the best value for ur money.

For extreme i9 overclocking, robust VRMs and comprehensive BIOS control are crucial. High-end Z790 boards are your best bet. Look at the Asus ROG Maximus or MSI MEG Z790 Godlike for top-tier power delivery and cooling.
