This forum is coming apart at the seams in some places.
This thread is running long - 25 pages now:

There are a few people who just keep posting asking the same questions that have already been answered, or echoing things that have already been said. These posts are basically because no one wants to read 25 pages before posting, and they then ironically post the same thing again, increasing the total to 26 pages, 27 pages, and so on, increasing the likelihood that it will just happen again.
There are forums that are leaders in this space.
On Reddit, every comment can be upvoted or downvoted. Often the most common sentiments aggregate at the top, and then whatever related comments or echoes that occur become replies to those top comments, instead of scattered around the thread as you have here. This lets someone scan the first 5 posts for example, and get a pretty good summary of what's been said.
On Stackoverflow, answers that solve the originally stated problem rise to the top. Idle discussion is separated into comments, a separate entity, and more limited.
Choosing a format like these is a difficult decision, but either would do a lot to prevent people posting the same, answered question, over and over again.
Perhaps the most salient feature of both systems is both have a downvote feature. Stackoverflow takes that one step further and lets you mark something as a Duplicate. Both are essential parts of making large discussions scannable to improve the signal to noise ratio.
It might also help if your most popular models, like the R7, had their own dedicated section. R7 posts have been landing in both "Notebook" and "Ultrabook," and there's no clear way for a new user to scan for content relevant to their R7.
