For the information of those in the UK & EU, back in October I sent off my Aorus RX 580 to Marek, MVC's European representative in Poznan, Poland, for flashing. The UK seller of MVC flashed nVidia cards, MacStore UK, briefly offered pre-flashed RX 580s, but didn't offer flashing for customer cards, despite my entreaties, and are now back to selling nVidia cards only. Between the card making its way over there, five or six working days, Marek taking a few days to mod the card, and then the return delivery, the whole process took about three weeks from start to finish. Due to an unfortunate accident with a can of canned air and my flashed 4,1, on the very day I put the card back in, I've only got it back in a working system today (lengthy and unsuccessful repair process eventually resolved by getting a genuine 5,1 as replacement). Marek's services get an enthusiastic recommendation from me- excellent communication, prompt service, and he did a great job. The card has zero performance issues, and looks as good as new, no issues with port alignment. The Aorus Graphics Engine utilities for controlling settings under Windows 10 work as before, despite the EFI changes, which is handy.
Marek is also doing Vega 56 flashing & pre-flashed cards.
