to me even if you got a ''overkill'' card as they claim you got a card you can move up if you do a higher end build not then wishing you had got the 1080 in the first place
like my 980 ti all you see is that overkill for 1080p I don't seem to have any issue using it and if I were to ''move up '' in a monitor I still got the better card to do so not looking to rebuy another card ??
in the end all you can do is what YOU feel is best for YOU
good luck and enjoy
