    My original HD4870 display card in MacPro 1,1 just died. I am running OS X El Capitan with Pike bootloader.

    I still want to try last effort in order to see if I can repair it. After trying a PC card of AMD R2 230,
    the diagnostic LED "CPUB" on motherboard will light up. But I am sure the two CPU are all fine.

    Then I tried my old X1900, it can boot but the screen is always in low resolution.

    PC version of AMD 7950 is still very expensive. With the same price, I can get AMD 460/470/480. Does anyone know if new these 460/470/480 card work in MacPro 1,1?

    Be careful with the RX range at the moment. There are certain brands that work better than others. If it were me I’d get a cheap card as well as a usual one as a backup. A 7300GT must cost next to nothing surely?
