Do I need a third rack?

Reviewers are split. Some praise the extra cutlery and utensil space, while others — including multiple commenters on r/Appliances discussing the Bosch 800 — call third racks awkward or 'useless' depending on what you wash. If you cook with lots of long utensils or ramekins, it helps; if you mostly wash plates and pots, it can crowd the upper rack.
