yea dont buy last gen cards right now, with new gen cards coming out this year buying 10 series nvidia cards is the better play, in terms of ability to recoup investment by selling the hardware down the line.

The market for 980ti's will die completely with the release of next gen cards when there is a large supply of used 10 series cards being sold.

Right now best play is to buy any 10 series GPUs at or below MSRP, should make decent ROI.

(i.e. 1080ti's at or below 700$usd).
