From what I understand, DVI is superior only because it is a digital signal and, therefore (presumably) cleaner input. VGA connections are quite acceptable, however, as long as the components are quality components and all connections are tight. From my electician's background, I can say it is most typically the cable connectors that cause issues. And while the card may indeed be at fault, don't throw it out as bad until it is actually verified. Different cable, ideally the card installed in a different computer, and particularly with two or more different monitors all reproducing the same effect would prove it. Short of that, there is no guarantee it is the card as you claim.
With all that said, a digital input will tolerate poor connections better as they are designed with built in variability that the VGA and other analog inputs must interpret as different signals (by design). This is the true reason DVI is considered better than VGA (or digital is better than analog). It is the built in variability tolerance of the design.
