The new investigators and ancients ones are nice, but we never use the board because it really isn't very interesting.  If you use this board you have to dedicate 1 investigator to running around on that board all game and never closing portals or collecting clues.  It's pretty pointless.  We do use the 2 new "other worlds" and their corresponding portals.  We just put Dunwich over top of this board to show the other worlds only.
