Bro, I got me a MEG Z790 ACE. I'm running 13900KS, 4090, 128Gb DDR5 6400, (2) 2TB M.2 990 Pro and a M.2 2TB Evo. I also have a SAS RAID 6 42TB. This motherboard is great. When it boots, the BIOS also encapsulates the RAID card BIOS as if it's part of the MSI bios. I didn't have this on my ASUS motherboard.
Yes, I think all z790 motherboards are all over the price at least when I bought them, but the quality seems to be worth it if you plan to have it for a few years.
Also note, MSI BIOS doesn't visually look as good as some others out there look, but it gets to the point. I been an ASUS guy for a long time, and after I moved to MSI, I haven't looked back. I also have an MSI laptop running a 3080Ti. Love that too.
