We've created a new Forum under "Help" to discuss hardware in jME. Anything about graphics cards, CPU's, suggesting minimum/recommended hardware configuration, and performance benchmarking is welcome here. We've already moved some topics in the Hardware forum so you can get an idea of what belongs.

I think we should more think about a forum for installation-problems. As this people seem not to search the forum and pollute the other forums. if all the topics of a specific installation-forum are from the beginning installation-related they might read former posts. Maybe…
