There's never any point upgrading to 'get ahead' of future games. Because if your system copes fine for now, you don't need an upgrade now.
And if a new game comes out in (let's say) 6 months that you do need new hardware for to enjoy at very high settings, there's a very good chance that also new graphics cards / processors / other hardware will be out too. And so you could buy something even faster that what you can buy now for the same price.
You'll eventually need a new GPU. But increasingly with modern AAA games you may also want a new CPU too. Which as @OsaX Nymloth
says, you can't upgrade without also a new motherboard and new RAM.
So hold fire on the upgrade until you actually need it.
If you are still gaming at 1080p 60hz, consider an upgrade to 1440p 144hz with adaptive sync: a triple upgrade - resolution, refresh rate, and synchronised framerate. Monitors of that class are more plentiful and more affordable than ever. You'll probably want a new GPU for one of those. Perhaps look into getting a new monitor and new GPU once your existing setup no longer satisfies you.
