I am used to Intel and their BIOS and features so I like to stick with it. But yeah HEDT is nice but very expensive now however I would bite the bullet and cry my way to purchasing it, however I more and than likely won't have to.
If you pick the new Intel, you will find out how many options are different in the BIOS than in the previous generations. All basic options have remained the same, but you find the same on AMD mobos. All options are the same as on HEDT mobos ... as long as a manufacturer decides to include them. IPMI functionality is only for higher workstations and server mobos. HEDT generally doesn't have that. There are exceptions, but they will cost $1k+.
I also can't see a significant difference between AMD and Intel temps/wattage right now. It was huge in the last gen, but the 265K runs at about 180W under high load, and the 285K is maybe up to 220W. This is about the same or less than Ryzen non-X3D options. I don't get where some reviewers get their numbers, as some in early reviews suggested 300W+. Tests generally show that AMD is faster (not talking only about games), but I also don't get that online fights when everything runs great on both brands, and the difference barely shows an advantage on any side.
I'm not sure what new Intel updates will bring. There will be a new microcode soon, and I know there will be Gear 2/4 improvements (at least ASRock mentioned it for the upcoming BIOS releases). However, this is only about CUDIMM, and you can't get CUDIMM at high capacity right now. Well, you can barely get it in any capacity.
I still feel like the market focuses more on Intel products. AMD motherboards are improving compared to Intel options, but when you test multiple of them, you see that something is always missing, and AMD is still considered more for home entertainment than work.
It's a bit weird that the HEDT/IPMI options are mentioned, and the next Z890 Unify-X appears
If you want OC mobo, look at ASRock Z890 OCF. I have one in tests, and it runs great. It also has great support from ASRock/Nick Shih team, so you can expect many updates quite often. They have already released 20+ BIOS versions and the next improvements in RAM support. ASRock also costs almost $200 less in stores like Newegg.
