I'm going to be adding an outboard graphics card to my PC. It has,
one each, a DVI-D, a displayport, and and HDMI port. My two monitors
both have DVI-D ports. I know I will need to get an adapter cable of
some sort to connect the second DVI-D monitor to either one of the
other ports. Which one would be best the displayport or the HDMI?
FYI, my second monitor also has a VGA port that is currently how it
is driven.

You didn't tell us the native resolution of the monitors.

DVI-D ------------------- DVI-D monitor (dual link for
2560x1600 ???)
(single link for
1920x1200 ???)

DisplayPort --+--- active_adapter --- VGA $20 (uses +5V
on DP cable)

+--- passive_adapter --- single Link DVI-D

HDMI ---------+--- active_adapter --- VGA

My primary monitor is 1920 x 1080 and my secondary monitor is 1600 x 900.
That one is mainly email and a couple of status monitor programs there is
nothing very demanding going on there.

Right now I am leaning toward an HDMI to DVI-D passive cable. According
to my research, the digital signals are all the same, with the only
difference being the type of connector on each end. And like I said in a
different post, no sound to worry about.
