Lol omg .. your link never helped me at all =D .. It just confussed me even more, so the link you gave me (The $165 one) is the best option out of all of the links above?
I was basically giving you a comparison between the two (as mentioned above)! With a ATX tower I will as well recommend ATX boards over mATX for the expandability. In regular use the PRO would only be needed for a dual GPU setup, most other features are comparable.
