OK, so I've seen the statement and head-shaking more than once on this forum about people putting 780 or 780Ti in a build that's mainly for WoW, saying, "Why do people overkill??"
I'll be putting together a new build this summer with a focus toward 20-man Mythic raiding in Warlords of Draenor. Is it a certainty that a 780/780Ti will still be "overkill" in the new expansion? Would I be better served putting that money elsewhere? Or is there even any way to know yet?
