I need to learn what the latest sockets or chipsets or whatever fit into the best motherboards, and what technologies are actually useful and which ones aren't (SLI). I've tried a google search, but nothing has come up. Anandtech.com doesn't really have a beginner section. Are there any sort of links or guides that could explain that stuff to me and places that have timelines of when these new things are coming out? I want to build a new computer soon, but I keep reading people saying to wait.
