I have a dell Dimension 8400 that i've just finished doing a pc restore and I don't want to mess up my computer now that it is working.  I did have Dell support 3 (DS3) and was liking it.  i've installed Dell Suppor Center and have Dell Support V 5.0.0.630 already running.

are there any issues i should know about if i want DS3... do i need to uninstall DS v5 first?  has anyone been getting unnessesary or conflicting updates from DS3??
