It's a courtesy. I'd try to get the other spot to push the date out by a week. If they are unable, resign "Effective Immediately" or with a one week notice. Either way, you come first. And if YOU need a week to decompress from one before starting another, then YOU need to do YOU gotta do.
I've done all three. It's not hurt me one bit in my professional life.
