Any Z790 is pretty good.

Leaders based on my personal experience is any Asus ROG series.

Since you already had DDR4, that makes complete sense. I sold my ram, mobo, and CPU when I went to a 12900k.

You can fit obsolete tech to new tech. I believe a better option if you want to save money would be to get a cheap DDR5 kit and a DDR5 capable board and, in a couple of years, upgrade the ram to a nice overclock kit.

By obsolete tech I didn’t mean it’s no good, just that you’re committing yourself to a product that’s being phased out.

I might need to read more tests, but I had believed we passed that point at about 6200mhz on most kits.

DDR5 because 4 is obsolete and why by an obsolete mobo to suit obsolete RAM?
