Is there anything fancy about the nozzle or is that just the general grift companies are doing with replacement parts?
First of all: Nozzles are replacable and they are also cheap. They are also wearing down with time. So if you worry, just replace the nozzle. And if you want to know if there is still filament stuck in there, unscrew the noozle and look at it.
Just be patient. Those new GPUs are so new, expensive and rare that no game has them as target hardware. Stay on your current setup and wait until games are catching up and prices go down.
