Help me pick a laptop

[PriceDemon]

I'm looking to buy a laptop and i was hesitating between 3 models.

1- Dell inspiron 5559 ($790)
i7 6th generation 6500
16 GB RAM
2 GB AMD Radeon R5 M330 graphic card
480 SSD

2- HP pavilion 15 ($828)
i7 6th gen 7500
12 GB RAM
2 GB Nvidia 940
1 TB

3- Dell inspiron 5559 ($680)
i7 6th gen
8 GB RAM
4 GB AMD Radeon R5 M330
1 TB

I generaly need this computer for photo editing, med level graphic designing, browsing and maybe a little gaming from time to time. Not the heavy type of gaming, I have ps4 for that.
I take good care of my machines so i need one to last 7 years. I don't want its specs to go dated in few years.
I care about ellegant design that's why I'm considering the Hp.
I wasn't planning on spending more than $700 on a laptop.

Which one do you think is fair for my needs? I'm open for suggestions too and would appreciate any tip.

For photo editing choose the one with better GPU.
