Yet another thread? Can't stay indecisive forever ~.^
Sorry, but I gotta disagree with this. Now if the OP wants a console just to avoid the hassle of fussing with computer specs, sure, more power to him.

Editing because I'm running up against the stupid daily post limit. Here's my thoughts:
1. Solid gaming machine that sticks to the basics with no frills. Oh, someone going to complain it can't do good graphics? Hahahahahaha.
2. Same as above, but with a slightly worse video card in exchange for a slightly better CPU. This might be a good trade off for video editing or something but for gaming... #1 is better.
3. ...Video GPU is nvidia but has less memory and performs slightly worse than the R7 250 (but only very slightly).... I wouldn't bother with it
4. Same video capability as #1, but with a bigger hard drive and an SSD and a stronger CPU. So it gives you some room to grow. As discussed before, SSDs do give you better load times but any desktop hard drive will be faster than your old notebook. So, do you want loadtimes to be lightning fast? (I won't deny it; like a performance car, it's really nice... but it's also a luxury).
Honestly, you won't notice the CPU difference unless you edit videos, encode DVDs, run some really intense simulations (they kind they do in universities, not ones branded Microsoft or something)....that sort of thing

It is worth noting that, as others say, you do get the best bang for your buck building your own. However, the markup from those smaller names like the ones you link to is considerably less. So... if you want to go that route, it's really how comfortable you are with building a computer (go on youtube and search around, lots of guide videos).
The console route is also viable if you just don't want to deal with all this. xD (But you would need to buy FFXIV for the PS4 to move your account over)
