It is shown that--at a small fraction of computational costs--SAPT(DFT) can provide similar accuracies for the interaction energies as high-level wave-function based methods with extrapolations to the complete basis set limits. This accuracy is significantly higher than that of any other DFT or DFT-based approaches proposed to date.4 pages, 3 figuresChemical PhysicsAtomic and Molecular Clusterstext
