I want to get a Mac mini, primarily to use Plex or XBMC to host media (streaming to jailbroken AppleTVs/Roku around the house). I also like having a "hub" at home (recently sold my Mac Pro... only laptops in the house now!) to both host files and to give me a computer to remotely log into (to queue downloads from afar, render things, etc). Since I've never had a home media center computer before, how important is dual-core vs quad-core? I know the "server" version is quad-core, does this make a difference if my wife tries to stream a video on an AppleTV while I try to watch something from the Mini? (Or is this something that either processor would struggle with?) I guess I'm wondering if I can get away with the base model for my use or if the quad-core would be better for it.
