If I cared that much about cost / performance I would get another Xbox Series X. Cost effective isn't the aim here.
Fair enough, as I said your money to burn. Also an Xbox isn't the same as a PC, I can't edit photo's and video on the Xbox, to name one thing.
The attitude you are displaying here isn't going to win you anybody's agreement btw, since a vast majority will go on evidence based decisions rather than emotional ones, so as you said wait two weeks and you might find some agreement, but leaked CPU-Z screenshots aren't helping your argument.
