Just a suggestion but for questions that we see that start to create a duplicate ripple, why not create a question to rule them all. For example, for the Low Graphics ModeLow Graphics Mode how about create a question that has most of the information gathered from all of the answers provided or a general step by step way to solve most problems related to it.
Same goes for slow, error and other tags. A single, community wiki question that has multiple answers that can answer most users, eventually helping out the moderators, the clean up done in the future and saving a lot of time. I could help with this if the community thinks is a good idea as well.
