just got a sapphire rx 480 8gb nitro+. but when i put it in the machine the monitor just stays black. the card powers up, the lights are on, and the motherboard vga output won't activate if the card is in (works fine when i pull it out).
seems I'm seeing this posted a bunch of other places, there is a guy below with the same issue with a 470. did they just make a bunch of faulty cards or is there some other issue that i need to address with my machine?
upgrading on an I-7 3770k from a amd 7770hd to the 480, i was expecting a smooth switch.
