Notes:
- h/s values based on public published benchmarks, but source and version of hashcat varies; YMMV.
- See epixoip's gists for full benchmark results: https://gist.github.com/epixoip
- Where I use other people's benchmarks using multiple cards, I use average h/s across all cards.

Other recommendations:
- Watch local electricity costs. If you run long hashcat sessions, use power-efficient cards.
- I like the EVGA GTX 970 SC ACX 2.0 - for price, performance, power draw, and temp performance. 
- But note this is a non-reference card; reference cards (usually single fan) are considered superior.
- The GTX 980 Ti is best for hash-per-watt, but two GTX 970s will outperform - for less hardware cost.
- You can put six 970s in one open-air chassis, and draw <1000W from the wall at full GPU load.
- Nvidia is better than AMD for overall driver management and reliability.
- All signs point to AMD collapsing as a GPU player. I wouldn't invest in their newer cards, either.
- Don't get a GTX 480, even at a good used price. They run *very* hot.
