Generally, you’ll get better results by spending half as much on GPUs twice as often. Games generally aren’t made expecting all their players to have a current-gen top-of-the-line card, so you don’t benefit much from having a top-of-the-line card at first, and then a couple of generations later, usually there’s a card that outperforms the previous top-of-the-line card that costs half as much as it did, so you end up with a better card in the long run.
