Pretty soon I will be moving the computer from the upstairs bedroom to the basement. I have my 'man cave' set-up in the basement. Planning on connecting the audio into my Sony ES 5.1 system. Then I have some good Polk Audio speakers.
But I don't see the reason why to upgrade to an audio card. Working in the tech industry, I don't see too much upside. But then this computer is overkill, so what's another ~$100
Maybe when I update my 5.1 set-up in the 'man cave' to a 7.1, I will get an audio card.
Here are some pics of the 'man cave.'
You are correct, two separate 20A lines. Will be hooking up 2 new lines in the basement, just for this computer
