So I'm thinking about getting this speaker system, so of course I need a receiver to pair it with. I've never owned a receiver before so I'm not sure what to look for Primary uses: Computer sound - Undecided on whether to get a soundcard. The motherboard I'm getting uses the Realtek 892 chip. I'm sure a soundcard would be a good idea, but I think I'd like to at least hear what it sounds like before hand. Xbox 360 - One of my concerns is whether or not I should use the HDMI input from the 360 to the receiver and then the television, or if I should bypass the receiver with the HDMI and just use the optical the reason being I don't want to introduce lag into the system. Is this a concern? Beyond making sure it outputs enough power to the speakers that will be connected to it what things should I be looking for in a receiver?
