Try it out first, see how you like the performance, if you do, which you probably will, stick with what you’ve got, save your money and upgrade when you hit an eventual wall down the road, like you “can’t play a game that you want to”, then do a decent generational upgrade, the longer you hold out, the better the stuff you will end up with. By the time that happens you will probably want a new GPU too, and on and on it goes. Don’t get all bent out of shape about words like “bottleneck”, unless something isn’t performing anywhere near like you expected it to.
