Do cables make a difference? That is an argument that will never really be settled. My two cents is that they do for analog signals but much less so for digital.
My experience with DVI/HDMI is that either it works wonderfully, you get green sparkles, or you get nothing. I agree that for long lengths, quality counts, or maybe a more expensive cable will last longer, but if it works, I don't think spending more money on a DVI cable gives you a better picture.
I've got a $100 DVI cable and a $10 one. I've used them both with the Accupel signal generator and the multi-burst pattern (tests resolution and artifacting) to see if there was any difference -- not to my eyes.
That being said, there are worse ways to spend your money than buying quality cables, and I tend to error on the side of quality since once the cable is up in the ceiling, I don't ever want to have to replace it.
