My 780 (3GB) is probably dead. It served me really well, only having to turn off the super fancy anti-aliasing, shadow, super resolution etc. settings and being able to play the rest on Ultra. But given that, and the aesthetically-pleasing likes of Cyberpunk (pre-ordered), Watch Dogs 3 (WD2 had its slowdown moments) and Star Citizen (coming in 2032 Q3), an upgrade was probably due anyway - just have to do it now instead of when the requirements are published. So I know it's all speculation really, but use your vast experience and knowledge!
