Are there any advantages of doing a Fresh Install instead of just upgrading the current OS when installing Snow Leopard? Just upgrading is a lot easier since you do not have to reinstall all your programs, settings, etc. but I wonder if there might be performance issues. I did the upgrade option on my Mini Mac that is media server when installing SL and have had PLEX freeze a few times and thinking about doing a fresh install to see if that helps. My imac though I really want to avoid of having to reinstall all my programs and getting the settings correct again. I understand if things don't work correctly, then do a fresh install of SL. My concern is if I do the upgrade path, things will work fine, but I might have had better performance if I did a clean install but would not really know since I could not compare the two. Just wondering if anybody had performance issues when doing an upgrade instead of doing a clean install.
