Before looking for used Nvidia cards check your requirements first.
During the mining craze a bunch of cards were released targeted at the
miners, and they came with only PCI Express 1.0 with very limited
bandwidth (compared to the standard PCI Express 3.0).

The mining cards can be fine if your data can fit into the card's
memory and it just sit's there being dealt with, but if you need to
transfer data frequently it could be a problem.
