I'm thinking of ditching my current 2.1 pc setup and getting the Boston Acoustic soundware speakers and an accompanying Sony...DH820 AV receiver. As everything will be connected to my pc I'm wondering how to go about setting and connecting the above package up? My Samsung Led is used as a pc monitor and is hdmi'd into a nvidia 680. Sounds like a stupid question but I'm assuming I would need to buy a decent soundcard as well. Thanks.
