Although I do have another question -- is there any benefit to moving to display port? I'm guessing no but I don't know.
Most of the advantages are in the technical details. For typical usage scenarios it won't make a difference whether you use DVI or DisplayPort. If your video card and monitor both support DisplayPort natively, go ahead and use it. Otherwise, don't worry about it.
DisplayPort (like HDMI) allows audio to be carried over the video cable, which may be useful for multimedia (HTPC) type applications. It also tends to be used on video cards that support large numbers of displays (e.g. the 6-head cards from ATI), since the smaller connector size makes it possible to cram more of them onto the bracket.
