So I bought a Zotac 1080 ti and it would cause my screen to become green/static whenever I manually changed the refresh rate higher than 60hz. I therefore sent it back and got a refund thankfully so I am looking again for another 1080 ti (or the same if its another issue) or a fix. my current build is as follows: i5-4690k, msi z97 gaming 5 mobo, 16gb ram, 80+ EVGA PSU, and a gn246hl monitor. I was told that a 1080 ti would be bottle necked by an i5-4690k and was wondering if that was the true issue. Either way, sorry if I respond late and thank you in advanced if I personally forget to do so!
