Isn't it just software? If so, I would think it'd be mostly useless as it'll still be dependent on the laptop's DACs and output, and since its software, I don't think it'll boost gaming any (well it should sound better, but its going to be at a performance hit).
I don't know for sure what audio chip it uses, but I think it should at least have Intel's Azalia, although I'm far from certain.
