1060 can handle most latest titles at 1440p, but a lot of them need a lot of graphics settings tweaking and it really doesn't hurt to use freesync/gsync.
Not gonna last I'm afraid tho. As for me, probably gonna endure it until Hopper 5nm in 2021 equipped with something to compete with the new on the fly SSD DMA compression/decompression thingamajig. I doubt Ampere or RDNA2 has that, but Hopper and RDNA3 should.
I don't expect neither Ampere nor RDNA2 to age well if they lack this feature...
