Debating between a laptop and a desktop.

[RoxasA]

Hi! I hope I make this thread correctly and won't end up with it closed, if anything is wrong or against the rules then I apologize in advance.

I'm looking to buy a computer over the next and debating between one of the following, with a laptop the top choice due to mobility (even though I know a poorer choice, sorry.)

The laptop is this one, the specs are the following.

Dell

i7-6500 - 2.5 Ghz with 3.10 Turbo
Intel HD 520 Graphics
12 GB Ram
Windows 10 64 bit

And then there's this desktop which I'm iffy on.

HP

i5-6400 2.7 with 3.30 Turbo
Nivida GTX 745 4 GB Graphics
12 GB Ram
Windows 10 64 bit

I'm mainly looking to run SSBM, Zelda SS/TP, Tales of Symphonia, etc. I don't really care for anything about native resolution, but the higher the better. I would prefer the laptop, but couldn't find much regarding Dolphin and that processor/Graphic

Thanks!
