it is my understanding that the Turtle Beach Montego II uses the Aureal Vortex II chipset. So unless the vortex 2 card you are referring to is the latest that supports 4 speaker sound or digital output, they are probably about equal. Which sort of makes sense, given the price.😉 On the other hand, at least Turtle Beach is still around, so maybe the Montego II will be supported for at least a little while longer, so may that may be the better way to go. I hope so because I just got my new Montego II a couple of days ago and am installing it right now!😎
