Hi,

Im gonna buy some rx 580s, but I noticed there are many factors to consider...

I have the choise between

SAPPHIRE Radeon RX 580 NITRO+ Special Edition 8GB OC (the blue coloured)

MSI Radeon RX 580 ARMOR 8GB

SAPPHIRE Radeon RX 580 NITRO+ 8GB


i will be mining etherium. which one of these is the best card?

I know that with sapphire cards it is better to have SAMSUNG memory rather than hynix, is this correct?
How do I know if it has samsung or hynix before I buy it? There is nothing on the manufacturer website /datasheet.

Also, can you please tell me if there is a big difference in power consumption (watts) between the cards? And what's the best card speaking about temperatures?

thank you ^^
