A:AnswerAey up! Can't see why not. You'll have to remove the drivers of the Radeon card before replacing the card & DL the new drivers for the RTX 3060 card, (this way you'll already have what you need to get r done). The BIOS will take care till you can get the new drivers loaded.
Hope this helps ya out. Dam good card!
A:AnswerYes, this GPU can support audio through HDMI. However, you need to be sure that the device that you are plugging into can support audio via HDMI. - KP
