Market segmentation is always better if you can pull it off. That way you can optimally serve two demand curves instead of just one. Sell more units at a lower price to gamers, for higher total profit from gamers, and sell at an even higher price to crypto miners, for a higher total profit from miners.
And those miner cards can't become gamer cards so gamers will need to buy a new card instead of an old high end miner card when crypto falls out of style again.
