I confess, my reaction to the PartsPicker revelation was: well yeah, we knew that. I have known of the site but never actually used it. I think, and I might be a bit jaded, that it is more for novice builders. It does however have a feature that allows one to share your selection of parts with others for "expert" opinions.
One of the tech sites I visit regularly refers folks there for suggestions for "what video card should I buy?"
Certainly worth keeping in the tool bag.
