The ASUS GTX 550 Ti DirectCU TOP has moved away from the NVIDIA
reference design chosen by some manufacturers. The first change was the
mini-HDMI connector, replaced by a full-sized HDMI, and the addition of
a VGA connection, replacing the second DVI connector seen in reference
design cards. As with the GTS 450 and GTX 460 it features bitstreaming
support for both Dolby True HD and DTS-HD Master Audio, handy for home
theatre PC use.
