Its not just Asus most manufacturers are shipping more OC versions, my guess is it simply comes down to their profit margins as they clearly make more money on overclocked parts. But as long as they keep shipping then that is what matters.
What is most annoying is when board partners create totally new SKU's and then release those and then ship stock, this greatly annoys myself because they have used 3080 GPUs to make those cards which have no back orders when what they should be doing is purely focusing on fulfilling back orders on all the SKU's they already sell.
As such I am on your guys side, I even tell the board partners this and ask them what the hell are you doing making and shipping new SKU's when you still have thousands of back orders on current SKU's, of course they do not answer, but to me its a bit of a joke and not too professional for me to post as such but its the truth, every board partner right now should be using every GPU they get to make more of the products they have back orders against and not be making new SKU's.
