If RGP cables can handle 1080i, there's no reason they can't handle 1080p. One reality that's often ignored in the cable business is that ordinary RG-6 has plenty of bandwidth to work as a video and digital interconnect.

If you use lower grade RGB cables could it impact the image stability?
I notice what appears to be image overload during busy scenes or high contrast segments. It takes a moment to refresh, and then functions as normal.
As far as I know, the only interface that can convey 1080p is DVI or HDMI, so the question is moot. When you say you notice that the image appears to overload during busy or high-contrast scenes, are you really watching a 1080p source via RGB? What exactly is your setup (source, display, interface, cable)?

Motorola Comcast box using RGB into Pioneer AV Receiver, RGB out to Mitsubishi DLP, with source of 1080i broadcast through Comcast box.
I've recently upgraded to HDMI through the Receiver for DVD but want to know if it's necessary for the cable box.
If you got good result from your DVD player via HDMI, then that might also be true for your cable box. The only way to find out is by trying.
I have seen some glitchy cable video via HDMI. I was at a friend's place in NYC and he was having trouble getting cable images to center up on his Samsung rear-projector. The images were offset for some reason. When we changed HDMI to component analog, everything looked good--problem solved. Many custom installers say they run parallel digital and analog cables because of problems like this.
