In the US, release price of GTX 580 was $500 and release price of the 1080 at launch is $600. Converting the 580's price to 2016 dollars gives about a 10% increase in price. The 980 TI I'm not sure is the best comparison to a GTX 580. It was intentionally a very expensive ultra-high end card. The GTX 590 debuted at $700. There does seem to be a problem with prices being ridiculously high in most non-US regions, though.
