IMO we are looking here at totally maxed out settings, HW inicluded in the witched 3 and MSAA in GTA 5. Far Cry 5 and Mass Effect Andromeda shows 30fps difference compared to 1080ti (and almost doubled minimal fps!!), and that's very big difference because when 1080ti will average 45 fps new 2080ti should provide finally solid 60fps or close to it in the most demanding games. Also keep in mind, the same game benchmarked in different benchmark locations/scenarios will give you totally different results. GTA 5 in one place will average 90 fps (city area), and can dip to 40 fps in the grass area so depending where you will test the game you will get different results. Witcher 3 for example in demanding locations can dip below 60fps even at 1080p on GTX 1070. It's very close to 60fps with HW on, and with OC I'm sure game will run at 60fps for the most part. With HW off you will see huge performance increase anyway and the witcher 3 can be played at 4K even on 1080ti OC.
