Welcome to the EVGA Forums
sorry your thread got stuck in the spam filter .. I've released it
I had 2 - EVGA Titan X SC & ran them in SLI
SLI "worth it" - depends on what your going to use it for
If your talking gaming specifically ... look to see if your game - Supports SLI & read reviews for other that play that game
What monitor resolution are you using ?
Not sure if there are any 'New Titan X SC" to be had though you can keep checking EVGA's
B-Stock & search other sites where used parts are sold
