Hi guys, I'm planning on getting the Sennheiser PC 360 and wanted to get a sound card with it since I would like 7.1 surround when I play shooters. As I have never gotten a sound card I have no idea what to look for. Any recommendations? Only important things are 7.1 surround and that it has an amp (at least I think an amp is important). I would like to keep it around $100, but I can go up to $200 I have to. Also feel free to recommend other headsets if there are better ones.
