Interior Wall Materials

[dude]

I have 2x4x16" OC Wood studs in an existing structure.
I don't think I can easily build a complete room within a room on a floating floor. So...after insulating the exisitng wall cavity, should I use RC channel and a layer or two of drywall,  or drywall ontop of soundboard, or drywall on top of 703? Or is this all a waste of time?
Any advice is appreciated.
