Seems like the motherboard quality is reflecting that. I just received an Asrock H570 ITX board which is 8 layer glass fabric and says it has an 8 phase power design. Not an expensive board.
What a pig!!
Every other cpu in that review is better! Glad I didn't pull the trigger on a z590 motherboard. Another generation of waiting, though I would like to tinker with a 5800X. Benching with 3090 would have been more appropriate.
Like I said, I do want to upgrade to an 11th gen CPU in a year or two, mostly for PCIe 4.
The gen 4 M.2 port on my board does not have any, only the gen 3 ports do.
