Usually the high-end cards like the *80 and the *70 series come first, then the *60 and *50 cards. The GTX 580 was launched in November or December 2010 and the 560 and 560 Ti came in January 2011. The GTX 680 came out in March 2012, the 670 in May 2012 and the 660 and 660 Ti in August 2012. The GTX 780 and 770 came out in May 2013 and the GTX 760 in June 2013. You get the idea. So if the GTX 1080 comes out at the end of May this year then we might be looking at a July, August or September launch for a 1060.
