Advanced Framing: Less Wood, More Insulation | Silicon Valley Zero Energy Home | methods may reduce wood use up to 20% & improve wall thermal resistance values 5 - 10%. This doesn't include the additional insulation value you get by filling a 2" deeper wall cavity with insulation. A standard 2x4 wall cavity would achieve R-13 when filled while a 2x6 wall cavity can achieve R-20 with the same fill materials. This is over a 50% increase in R-value, and insulation is pretty cheap.
