Best GPU for LUKS June 2019

[cyruspy]

Hi!, 

I'm looking for the best LUKS hashing option on a single GPU, at around the us$ 600 mark (+/- us$ 100). Anyone care to share their experience?.

Options seem to be RTX 2070, GTX 1080(TI?). Also interested in the lowest possible power consumption.

Options for local sourced GPUs (+10% for taxes):
