I've learned over the years at least in my own opinion that gameplay and frames per second (smoothness) of gameplay are up there if not more important that graphics to me. You can have the prettiest looking game out there but if its not fun and the performance behind it is sh** it doesn't matter to anyone usually.
This is a good deal JSJ 500GB goes quick if you plan on buying games digitally though, and some games like Halo 5 have insane install sizes with updates (94 GB). If that's an issue the 1TB console isn't a bad option, but if it's not a concern at first and becomes one later, you can just get this
