I keep hearing SLI is on its way out. Some games aren't supporting it, and didn't Nvidia take it away from the xx60 cards and below? Anyways I have a 1070 that I see is SLI capable. Was thinking down the road of an easy upgrade path. I am currently happy with performance at 1440p. Was just curious if people were getting decent results or is no longer worth it, I understand it's often game dependent. These days I mostly play BF or COD if I play anything.
