SAPPHIRE FLEX HD 7950 3GB GDDR5 OC WITH BOOST

Hi, I am building my first ever CPU from top to bottom. I am looking at this card for a 3 monitor set-up i just read that you need don't need a active display port to dvi with sapphire flex cards. However I click on system requirements and at bottom it says you need a eyefinity dongle and takes you to several to choose from. Do I need onr or not I dont want to have to buy one if its not needed thanks in advance for all advice positive or negative.
