Hey Guys. I am going to buy 6x Sapphire pulse rx 570 8gb. My electricity is really very cheap So I dont care about the electricity. Should I buy this graphic card? what Hash rate I will be getting for only one of these cards if I buy ? I am not sure if Sapphire Pulse is good for mining but my budget is not that good so thats why I wanna buy Pulse version. it's really cheap compare to Nitro ones.
