Do what i'm doing.. I currently have 980 GTX SLI.. I'm waiting for the 1080 TI's to hit.. Why bother getting a 1080 now when the TI's are going to baically ruin the Titan cause there so close to performance for $150 more then a 1080? (Roundabout).
1080 Ti isn't even confirmed to exist, the only information out is from people on various forums making stuff up and speculating.
