Hi I want to get a 27" with 3 Tb. Mostly I want it to store and share home movies and pics. Kids would use it for homework - PowerPoint, Word and web crap. - no budding graphic designers at home. Would the "base" one be all I (we) need? Is 8 Ram enough to start with or would paying for 16 be worth it? The ones with better graphics and processors would be wasted on us unless my kids wanted to use it for gaming? Will price likely drop once the new ones are out? Thanks for the help.
