Yeah a fair number of the people who got into mining based on 2 month payoffs of cards and in it to get rich quick have started dumping cards on the used market helping out a bit. With that said, it's still very profitable to mine so prices will likely stay up a bit. If your budget allows buying a higher end card even like a GTX 1080 COULD be a better option as there have been some good deals on them recently and miners generally don't like them because they aren't THAT much faster than a 1070 due to the increased memory latency of GDDR5X.
It really is a rough time to buy but you do have the option of mining with the card you buy and making some of the expense back. Before power usage my GTX 1070s are between $1.90 and $2.10 a day, the 1080 is at around $2.62 and my 1080 Ti is at $3.75 looking at them all right this second. Those numbers change all the time and were lower two weeks ago (and higher yesterday) but hopefully that gives you an idea if you want to factor that into buying.
