It's been awhile since I took basic algebra, but it would seem 76^12/25x=72000 seconds gives you the number of cards you need. If I did the math correctly you only need around 200 Quadrillion gtx 1080 cards to brute force 12 character hashes in 2 hours. So with GTX 1080 cards being around $700 today, you only need around 140 Quintillion dollars worth of GPUs.[/color]

lets start with,
gtx 1080 cost less than titan x and perform better.
so u should go with them.
next thing,
it depend on what alogirthim is being use..
a simple example,
8 gtx 1080 have the power to crack 200.3 GH/s per sec
lower case (26) + upper case (26) + num (10) + special char only !@#$%^&*()_+-= (14) = 76 power 12 is
37133262473195501387776 possibility , now do the math how long that will take u with 200Gh/s
