Summary: I only use the HDMI, so I can't comment on the signal quality of the DVI or VGA connections.
Cons: AMD linux drivers. They really need to work on them. Every few times I boot it comes up all fuzzy which is corrected by changing the resolution and changing it back. I have tried every driver package currently available with no luck.
Summary: The Good: Works very good simultaneously running a 1080P television through HDMI and a 1280x1024 desktop display through VGA. Playback of HD video quality is excellent, no jitters or visual artifacts whatsoever. Very happy with this card, a good choice for HTPC users.
