And there lies the problem, you "expect", you want, you "deserve", its your "birth right" etc, Two and a bit years ago, it was the norm to get a decent performance increase for decent prices. Not now, and for the foreseeable future. You'll get what you're given by Nvidia, amd and later on, Intel and be grateful (thats their attitude, not mine)! not least until the Crypto Merge happens and even then, I'm very doubtful about the numbers of used gpus hitting the second hand market. None of those manufacturers are here to "give you what you expect", they're here to make as much money off you as possible and the current gpu landscape is allowing them to do just that. You want expected progress?, then everyone , and I mean everyone, needs to stop buying gpus, full stop for the foreseeable future. That way they'll get the message, and bring out products with much more benign attitude, ie: cheaper than normal.
Now, going back to the 6500xt, that card is a result of the situation we're all in atm. Is it a dog? yes, is it castrated, yes, all those things and more. Its also a card you can buy , brand new, with warranty, for under £200. Does it game at 1080p? yes, but with severe restrictions in some cases, so what? Its in stock right now and someone who is looking for a cheap gpu to play his games on, now has an option other than going used. Its better than nowt or paying £400 and up for a non existent Nvidia card thats supposedly its competitor, the 3050. If I could get one cheap enough, personally, I'd rather have a 1650super, better card all round, no so sure about the vanilla 1650 though
