Just as a timeline..
AMD 7970 - December 22, 2011

GeForce GTX Titan - February 19, 2013
GeForce GTX 780 - May 23, 2013
AMD R9 290x - October 24th, 2013
Geforce 780ti - November 7, 2013
I think the real winner here is the 7970... it's still a very formidable card to this day. Especially considering where it stands in most games compared to a vanilla 780 these days.
Sadly just goes to show how slow GPU progression really has been these past few years...
