Hm... The solution after digging around seemed to have fallen into the "active" display port. Apparently if you have 2 DVI and 1 HDMI port, you can only use either 2 DVI or 1 DVI and 1 HDMI, the third one will be disabled unless you have an "active" display port. I'll give it a try when my order comes in and update this page just in case anyone else in the future might run into the problem.
