That depends do you need 2.5tb of storage? I am mainly a gamer with fast internet so I would have no problem getting the 500gb ssd and deleting and reinstalling games if I run out of room. At this point I wont even use an HDD for most modern games, you should see the load times for bf1 multiplayer on a hard drive truly ridiculous. But if you have lots of stuff to store other than games getting the hrad drive plus the smaller ssd might be the better choice, it all depends on what you want to use this computer for and what you have to store.
