1080 or 1080Ti 1440p.

[Guru]

If you plan to keep your card longer then get the 1080ti. If you are a quicker upgrader, then the 1080 would make more sense and you upgrade to something better in a year to year and a half from now (notice that would put the 1080 at two years old since release).

I upgrade my GPU with the help of this list GeForce GTX 1080. Hope it will help you as well.
