Do you find it worth it for the massive increase in bandwidth needed? The tracker I use haves 1080P rips that are around 10GB for a movie. Nobody ever really downloads that. The 720P versions are way more popular. They are good enough for people that don't buy gold HDMI cables.

People absolutely download the 1080p rips. 10GB is really not a lot with the bandwidth and storage available today in first world countries. You're certainly not getting into "videophile" territory when you can tell the difference between 720p and 1080p when viewed on a 1080p display.

Quality 1080p video looks much better on a large 1080p TV. If you were watching on a 21" monitor then it probably wouldn't make a difference. 10gb isn't much of a deterrent considering I have 10tb of space. You can get 2tb drives for pretty cheap these days.
