RX 460 2GB ~ 75$ each Opinions?

Hey people,
I recently grew an interest in mining and did some research for cheap cards I can buy in my area.
Someone is advertising Gigabyte AMD Radeon RX 460 Windforce Overclocked 2 GB GPU's.
Apparently somehow he got a hold of 100 pieces, and he's asking 75$ each.
Do you think it would be worth it to buy some and create a mining rig out of these 460's?
Its hard to find good info on the performance of these cards, but I expect something around 110 Sols for 80 W per card.
Do any of you people have experience with this card and can give a better estimate for their performance?
