SLI question 770 GB

Hey all,
Just had trying to make up my mind if I wish to SLI or not. when the GTX 770 came out I sadly bought the 2gb Model. ((I know benchmarks see 0 to no difference in the cards)) However I am tempted to buy a 2nd GPU from ebay. (aroubnds $150) Currently I run 36-46 FPS Maxed out at 5760x1085 and in 1920x1085 I get 120-140 FPS.

My biggest question is will SLI and is SLI stable for FFXIV to make it worth it. Or is it better to wait a few years Pick up a single beefy GPU.

Another Big question is I have the super clocked edition of the 770....if I buy another I take it I need another super clocked edition as well?

More or less This is a post of someone who can't make up mind Mostly about SLI on current GPU. I have the money now to buy the 2nd GPU but would mean not getting collectos edition of FFXIV...((Not a big reason to get CE, and well SLI should help out in all other games as well)

SLi is functional and issue free for me on FFXIV. As for the value, that's something someone else will have to answer, I'm still on two 660Ti's. (60@1080p everywhere but MD and the occasional hunt / explosive crowd)
