Solved upgrading my graphics card

[Amaterasu]

hi there,
i've been thinking a upgrading for a while now i have a nvidia GTX 560 and i was thinking about getting a Nvidia GTX 780 as my GPU is old now and with GTA V coming out soon i think it's about time also i don't want to spend to much. is there a better option that anyone can suggest i prefer to keep to nvidia as i know amd has had problems with games in the past
thanks

If I could crank up your budget a little, I'd go with a GTX 980 or get a pair of 960s and link them.
