The video card that came with my z420 is dying with screen artifacting and randon black screens. I think it is an AMD 7470. Since it's an OEM workstation card so not much labeling but it looks like model C264. I replaced it and the artifacting went away but it occured to me that none of the random video cards I have laying around support 4k and/or have Windows10 drivers. I can't get anything about 1024x768 resolution with the old AMD card I threw in since Windows is using generic drivers. Any suggestions as to what to replace it with? I don't want to spend a lot of money. It doesn't have to do anything but allow 4k video to play. It already has AMD drivers installed so an AMD card would be make installation a little easier
