I recently bought into a Gigabyte Aorus 5700xt. Are there issues? Well it depends on who you ask. I have not gotten any black screens or game crashes. These seem to be the major issues. I do however have a few things to nit pick.
I first did a full driver and Radeon software install (19.10.2) because this was stated to be the most stable driver per the community. The software was working fine for me, but I noticed the fans would not spin. Then I realized you have to disable the auto fan stop. Easy fix, but even with it disabled sometimes the fans wouldn't spin. Once I had gotten some load on the card the fans got jet plane loud. Also the performance/frame rates were a little below what I was expecting. I tried fixing this with Wattman by setting custom fan profiles and disabling enhancements, but none of those things really fixed anything for me.
I am used to using MSI Afterburner, and it was what I had initially attempted to use to control the card, but whenever I launched MSIAB my screen flickered every 5 or so seconds, and would not stop unless I closed AB completely. Minimizing it wouldn't help and the issue continued. This also meant the in game overlay was unusable because my screen would flicker every 5 seconds.
For a few days now I have been on a drivers only install of the latest recommended drivers (20.11.3). I used 7zip to unpack the AMD drivers. I went into safe mode and did a DDU of all drivers and Radeon software (as I did before with my INVIDIA drivers before installing the new card). I then used device manager to update the display adapters and did a driver only install.
End results are I can use MSIAB without any screen flickering, the card doesn't sound like a jet plane (can't hear it anymore), I do not have the Radeon Malware and performance killing extras, the performance of the card has bumped up to what I was initially expecting,.
