Great choice of cards, I bought 20 of these, and they all came with Samsung Memory, so thats a good thing.
The only problem with them is they are 3 slot cards, so they are much bigger than others.
However, if you are able to find Sapphire RX580 Special Edition, then that would be a better option in my opinion.
My Special Edition cards are all 85%+ ASIC Quality, where the power color ranged from 70-85%
Do you know how much each RX 580 will be worth? i only have gtx 1060 here running and planning to build a new mining rig can you give me some idea how much RX 580 each with samsung memory? if i have a very cheap or free electricity i was thinking that its more profitable than nvidia graphics card..
I got my Sapphire Special Edition cards from the local distributor in my country, got them got 315 US$.
Most 8GB Cards whether 570 or 580 come with either Hynix Memory or Samsung Memory, these can normally overclock to 2150mhz easily, Samsung can reach 2250mhz.
4GB cards can come with Elpida memory, which can barely overclock to 2000mhz.
