FTDNA:  Meaning of 37-Marker Matches FTDNA:  Meaning of 67-Marker Matches FTDNA:  Meaning of 111-Marker Matches (coming soon) These listings from FTDNA are useful with this caveat:  their cut-off points are a bit high.  So, don't write off a borderline match if other evidence suggests there should be a connection (e.g., they share an uncommon surname), in which case, look for "in-betweeners" that could bridge the genetic distance between them.
