It is also known that DVI *cables* have two significant physical limitations: (1) the plug is ridiculously huge, which makes running it behind existing walls a real PITA, and (2) signals degrade rapidly over a relatively short distance, so if you require a run longer than 5 meters you need to look to HDMI or component to provide your video signal.
And, not to be glossed over, if you don't already have all the needed multi-channel audio interconnects, having to buy these at the beginning of a new project can really jack up the cost of that project. With HDMI it is like getting audio for free when you purchase your video cable.
Anyway, this could go on and on and isn't really appropriate for this forum, I just wanted to go on record as saying that I am, for the time being, still PATIENTLY waiting for this 1070 to come out!
(I'd really like the new pre-pro, but that might be too much to ask!)
