The days of "buy an i5" are from when we were all kids and wanted to save every penny. Don't short your rig because you think you will only use it for gaming. Look at the processor recommendations for the new Fallout texture pack before you decide on i5.
On your pci-e m.2 option, I'd say go for it. It's snappier and will give faster load times. Old sata SSDs are fine, but they are outdated as of this year. Get a 960 evo 500gb for 250 bucks and don't look back. These drives are a lot faster and you can tell the difference, but only slightly and in loading screens.
Get a monitor before anything else. Make sure it has.
1440p or greater
23" or greater(prefer 27)
g-sync or freesync
144hz
If you are not using a monitor with these features, your money is better spent on a monitor. I can't tell you how much qol and compute power you waste trying to handle vsync with software(half your stuff) or just accepting screen tearing in 2017. The next gen of monitors won't even call this "gsync" it will just be w and w/o vsync. Eventually it will be built in every single monitor made(not that far off). It adds a minute amount of latency which is un-noticable.
Opinions:
1. Ditch the bargin basement PSUs and get a seasonic, the new titanium flagship is nice.
2. Build your ram for the video card you want, not the one you can afford. Look at the REQUIRED ram for a gtx 1080 and start with that.
Thanks, PS: don't build cheap if you have money.
