I have the money to either buy the 1080 or tlhe 1070 but dont want to waste money. The only game i play is wow. I do raid fairly hardcore and want to do so with no problems. is the 1080 an overkill? I have a gtx 560ti that I believe is going bad. when i hearth to dalaran it takes a min or 2 to actually move, and see my character. at the start of boss fights i lag out and cant do anything for a bit.
