So I'm building a new PC that will be used for day to day normal use, rendering, gaming, and maybe a little editing here and there and I got my hands on a brand new 5.1 home theater system. What would be the best sound card for a high end 5.1 home theater system without breaking the bank (~$200)? OR would the onboard audio of the Asus Maximus VI Hero suffice (I have no idea how the sound quality is)?
