Pretty sure most people don't care about losing 0.5% hash speed every 5 days since we already lost half our profits from last week.
It would be very helpful if we could confirm if the harsh rate drop is a hardware or a software issue with the RX400 / 500 cards. If it's a software issue this can likely be resolved by an update to the miner or the driver. I have many of the RX580 cards on pre-order and can still cancel this order. I'm sure many of us are in a similar situation so a confirmation regarding the issue would greatly be appreciated.
