Recently I've considered buying a 3000 series card to upgrade to from my old, dying RX580. The 3060 Ti is in my current price range, but would it be better to save for a little while longer and get a 3070 Ti? Or is the difference in performance only minuscule? I'd also like to have the possibility of running 1440p or 4K in the future, hence why I'm asking if a 3070 Ti might be necessary.
