I have an old Dell Demension 3100 computer with integrated graphics. Windows 10 installed but it is using the generic MS video driver and only displaying 640X480 low color. Im not looking for crazy performance and not a game player. Are there any ATI/AMD PCIe cards that I could get that have Windows 10 drivers for them? 1024X768 32 bit color would be fine for me. Thanks
RX 460 would be a good choice for your system.
What power supply are you using?
