I recently acquired a gateway dx4870-ur3d. Thought I would toss a evga 650w psu in it and a MSI Radeon RX 580 DirectX 12 RX 580 ARMOR 4G OC 4GB. Issue is I have been able to find very lil information on the pc so I’m not sure if this would work or if I would be wasting my time. Any help is appreciated.
