So, I think I have made an error in purchasing a new GPU. I found a RX570 8GB very cheap recently, and made the purchase to upgrade from my Radeon HD7870 2GB. (i compared the two cards and the RX seemed far superior to the HD) The price was too enticing and i noticed this GPU was a few years old, so figured it would be compatible with my old hardware. Problem: Installed the GPU, dont get any video out of the DVI/HDMI. (have not yet tried the Display Ports, as i dont have any compatible Monitors...) I feel as though the Mobo is too old for this GPU?? Mobo does have PCIe x16 slots. Have updated to latest BIOS Tried to put the new GPU in the 2nd PCIe 16x slot along side the current GPU to see if the PC even picked it up, but i have the same problem, no video out of the CURRENT video card when the new one is installed... as soon as i pull out the new GPU, video is back on the current GPU. Important PC specs: (Originally built in 2012) i7 3820 gigabyte G1 Assassin 2 16GB Corsair Vengeance DDR3 750w Thermaltake PSU. Please point me in the right direction. ThankYou!
