Kill-a-G

Hi guys & girls! I have problem with Asus motherboard Rampage 2 Extreme bios! Last bios update vase 2011. I purchase Sapphire rx 550 4gb graphic card (can't change between bios & uefi on graphic card, no switch). My problem is now that my motherboard can't recognize the graphic card due obsolete bios, from 2011 year. This is also the last update Asus created. I send to asus support about my problem and I was shocked with their respond about my motherboard is to old and they won't create new bios for this issue of my... Linus please help me with this problem. If you know someone who can create new bios for this motherboard. When I was younger without wife and children, I could afford to spend money on hardware, but those years are gone. I can not afford to buy new motherboard and processor just to play new games with my kids. Will definitely buy new hardware, when this motherboard breaks down. Thank you all
