GPU upgrade?

[SamyBoy13]

Hi there guys I wonder if it's a time to upgrade my gpu? Currently I got EVGA GTX780 SC ACX overclocked and I wonder if moving on to gtx 1080 will be significant upgrade? I just got 4k monitor but I mainly play cs go, gta 5, assasin creed etc.

What do you guys think?
My current spec:
I7 4770k 4.5ghz 267v
Msi z87gd65
8gb ram g.skill 2133mhz
h100i
AX760 PSU

Yes, a big jump in performance (about twice as fast):
