Help on picking GPU

[NoDoz]

I currently cant decide on what I should upgrade to. I have a single gtx 780 right now. I either want to get the fastest 780ti or get another 780 and go SLI. I am a little nervous about going SLI because I don't want to have issues. I mostly play Wildstar, DayZ, and Dota 2. I do play other games as well that are more demanding than those.

My monitors I use are 2- Dell 30" monitors running at 2560x1600. Rest of my specs are:
Asus z97 deluxe
i7 4790k
16gb 1866mhz ram

Thanks for any help.
