so, here is my 2 cents… I just built 2 pc’s one 14900k on z690 and another 12700kf on z790(max). what I’ve noticed, the Z790(max) boards all split their PCIE5.0x16 to x8 if you use the CPU attached SSD even with a pcie3.0 SSD this is a major problem unless you are using a x8 graphics card with pcie5.0 SSD. the Z790 standard boards have pcie4.0 SSD to CPU and pcie5.0x16 graphics does not get cut in half but they are expensive. You can get a MSI Z690 ACE for $249! pair that with a 14900k like I did and you have the best system you can get today (even better than a Z790(max) board. and memory OC’s to 6000Mhz no problem.
YES, big brains here-
