I always see the nvidia vs amd comparison, but people generally don't provide the full picture. So I'll say it.
Nvidia is generally faster for attacks including bruteforce, combo related attacks. HOWEVER, if you intend on running lots of rules and wordlists on fast algos with a relatively large hashlist you will notice that a 290x may give you close to double the perf of a 1080.
1x GTX1080: Speed 1000 MH/s
1x R9-290x: Speed 1999 MH/s
This was tested with HC3.0 on fast algo SHA1 pass salt with a large hashlist, wordlist and rules. << Take note of this specific requirement.
This may have changed with the latest version slightly in nvidias favor.
So while nvidia will win in MOST cases for power efficiency /value, it's not true 100% of the time. I think this is important as some people may believe getting an nvidia card will get them fastest hashrate under all situations.
If you are happy to put up with excessive power draw (especially through PCIE) and don't mind the noise, run a lot of dict+rule attacks on large hashlists for particular algos then AMD cards could be useful to you.
