I have two R9 270x AMD Graphics Card crossfired, that as been working perfectly fine until about 6-7 months ago. I have spent countless hours trying to figure out the issues to my problem and like many frustrated AMD customers, it seems that the drivers or the software is having some serious issues with Windows 10. I'm no expert so I can't pinpoint exactly what the root for the issue is but the fact that I (and many others) can't get answers for months and waiting on new driver update hoping that the issue is fixed is insane.
At this point I'm ready to switch my investment and business to Nvidia and never deal with AMD again. If someone has found a fix for this damn issue please let me know, if not, then take this post as a warning and steer clear of AMD products.
