Clearly I didn't write correctly. I'm considering to buy 1080 TI or RTX.
It depends what you play and resolution you play at. I have EVGA gtx 1080ti sc2 with 8700k and running none OC I can run Shadow of the Tomb Raider on max settings and get average 66fps at 1440p (SMAAT4x). With TAA only enabled and not the SMAATx2/4x then I get average 96fps on benchmark, X2 I get about 75fps average then x2 is the 66fps. I am looking at upgrading though to the TUF 3080 OC just because I can (technically can't though as no stock ha). ]
It is all down to your personal choice. Anyone can comment what they would do but do what you feel more pulled towards. If you don't, you'll regret it.
