This is in connection to my other thread based on the question of sound card to add to the SFF optiplex 980 desktop mini tower. As i'm looking at various sound cards and from help of atfjsl's power info. I was looking at the Niveda graphics card that seems to be abundence for this model computer(?) and if i have Realtech as the sound or audio drivers for onboard sound, would it matter if i attached graphics card Niveda that would use totally different drivers as far as i know(?) or it would just acquire its own drivers and no problem to now have new graphics card/sound card that could be accommodated with the electrical unit and be able to fit in the Sff?
