In my opinion as much as I prefer intel the AMD build is definitely better than the intel one as the AMD chip is a quad core over the intels dual core and some games wont even be allowed to run on dual core but if your an intel fan these quad or above only games are sparse and the intel chip would probably last longer. but the biggest difference where it counts is the intel build has a graphics card so you have to ask your self this question, "do i want an intel build with a graphics card and possible restrictions" or "an AMD build with a quad core" As far as expandability goes the AMD one offers obviously buying a graphics card with that quad core which would make for an excellent upgrade so keep this in mind.
Hope this helps you make your decision!
