i can only speak for the x570 i have now (i never cared about Gb, since they never matched specs/features of asus or msi at same price level), never again.
When you have qvl ram (tried 2 different kits) that doesnt even post at jedec settings/voltage on a +300$ board, while it works on all other boards i tried incl a 150$ msi, or wfi/bt turned off when you enable Erp, is a joke.
On 50 (personal) builds in the past 20y, never had issues with ram not even doing post.
So while this no "proof" compared to planet wide sales, when others do a decent job at half the cost, im done with Gb.
