If you want, you can use the HDMI to DVI dongle that should have come with the graphics card, and then your graphics card can transmit a high quality image and sound through the dongle. However, if you have a good sound card, you should just stick with the standard DVI cable. I would go personally use a DVI cable. Your graphics card natively supports it.
