I have no doubt the new cards will blow next-gen consoles out of the water by 30% to 50%, but the question of what kind of price-to-performance ratio they will deliver still remains open. Intel are reportedly gonna be entering the GPU market as well, but I don't trust them to price their products reasonably any more than I do Nvidia. Which means we're all stuck hoping and praying that AMD can deliver high-end performance to rival them, at a lower cost. Seems unlikely.
In any case, I don't plan to build another PC until we're near the end of life for next-gen consoles. By then hopefully "RTX 4000" series cards are available, so the 3000 series will be a decent value when buying used. I expect PS5 and XBSX will remain the value kings for a solid 3-4 years after launch.
