Is it worth using a sound card in newer builds? I noticed that on board sound is alot better than use to be. I have a X-Fi Xtreme Music sound card in my gaming rig on a XFX 780i Mobo. I am in process of building a HTPC and was thinking about using this card since the HTPC mobo doesnt have onboard surround. Just wanted opinions on if onboard sound is good enough for gaming.
