To be honest, the improved boost clocks would the the only reason to get these new CPUs. Base clock remains the same as the "older" models and only a 100MHz increase for the boost ones (well, the 3800XT boost is 200MHz higher).
Given that the non-XT parts have recieved a $50 cut over the official retail price, I'd go for those instead.
