AM4: How futureproof is R5 5500 or 5600 for new AAA games?

During these times I want to stick with AM4, but my R5 3500x bottlenecks my RX 6750 XT heavily in some games. Horizon Zero Dawn remaster runs at 100% cpu all the time with stutters and horrible 1% lows.

Currently here in Hungary, the 5500 costs €80, and the 5600 costs €130. I don't really wanna spend more than €150-160 at all, maybe only by a bit if it can last me a good while.

Should I get a different one? I just want it to not bottleneck for atleast 1-2 years at 1080p.
