Here is the current range of Desktop Boards. you could click on each one to see its feature set. I am aware that at least the DZ68BC has HDMI ports from the Extreme Series so there appears to be no hard and fast rule.
In the end it'll depend on what sort of things you want to use the board for/what your expectations are and how much you plan on spending as to which board is most suitable for you.
The DZ68BC has a HDMI port (and DVI and DisplayPort).
