I am upgrading this pcpartpicker list to a ryzen 2500x based computer. This pc will be driving a churches 2 monitors, 5600 x 1260 px projector wall, and streaming 2k video to youtube using the elgato 4k capture card. (we are upgrading so that we can stream, the old computer (amd fx) handled all of this except only streaming 720) We have a person willing to sell us a used geforce gtx 1080 for around 300-400$ (it was used to mine crypto) but we don't know if we need a new graphics card.
