I don't know about problem with AMD/ATI cards.. but with nVidia GPUs there's a know issue with every MoBo(ASUS, MSI etc.). There is a problem between the GPU BIOS and UEFI. For example 660GTX doesn't work on mostly any AsRock MoBo with Z77. So if u buy, try, if doesn't go, return it..
Yes, that is the problem ... Long post or even no post..Have you tried fast boot or ultra fast boot ?EDIT :Have u tried changing PCI EX from AUTO to PCIEX GEN3 ?
New UEFI-BIOS might help. Have you tried? Or BETA version..
