I don't think you will get the desired results, honestly...
...keepin' it real, here's what I use, which will actually allow me to maximize (or maximise) the settings to the highest levels:

Works as good as a desktop. Basically, consider it a mobile workstation, with built-in UPS battery backup.
As for my actual 'desktop', that is a homebrew build:
Storage = Samsung 850 Pro 1TB
GPU = eVGA's GTX 980 SC w/AC 2.0
CPU cooler = HYPER 212 EVO
CPU = Intel's i7 4790K (runs at 4.4 Ghz by default with the following motherboard)
MoBo = ASUS Z97-A/USB 3.1
Soundcard = Creative Sound Blaster Z
RAM = 32 GB of Corsair Vengence @1866mhz
PSU = Cooler Master Gold 1200w
Case = Antec 1200
I am not going to bother mentioning the DVD/CD-RW/Blue-ray, since most stuff is streaming or download. It is a cheap LG model, gets that rare job done when needed.
That setup runs ANYTHING at max settings. Yeah, I could upgrade more stuff, by why bother? I got 7 years out of my previous build, I probably get the same or more out of this one.
Anyways, bottom line, you are anticipating a lot from a system that seems mid-caliber, at best, in my opinion.
Goal for a system, to me...
i7 CPU minimum (K series will allow safely increase of speed if desired)
SSD storage
GPU, I say GTX 900 series as a minimum (maybe AMD R-480?) as I know that works good, obviously 1060 & up would be better.
On-board sound will get you by.
16 GB of RAM minimum should be a safe bet.
The PSU (power supply unit) should be better than average, and I recommend you avoid cheap ones, I am just suggesting it from experience. $100 or so, for a starting point.
I've used a PC parts picker web site before, maybe pricing is better now. Try it, it usually puts compatible parts together, to avoid conflicts.
Doing just the basic parts, and recycling the case (assuming you have one) and O/S:
