I am just preparing my pc for home Video capture & editing . I have P-4 2.8GH HT /1 GB RAM /865GBF Main board with on-board 6-channel audio & pinnacle capture device (USB 700). My Pinnacle capture device AND SOFTWARE support stereo input and Pinnacle recommends Creative Audigy type expensive sound card for it .
My question is do I require a separate Sound card for this job and how it is going to be better than on-board audio . Does my on-board audio not support stereo and surround sound ?
