That CPU is absolutely fine for gaming, if you're not interested in streaming or recording there's very little reason to go bonkers on the CPU, you'll generally see better returns investing in a more capable graphics card instead.

And on that note, regarding that graphics card, the 3gb 1060 is absolutely fine for stock games at 1080p, but you'll quickly outgrow it if you've got any interest in modding games such as Fallout or GTA. IMHO a 1070 is a better card to aim for even if you have to hold off on the purchase for a little bit. As others have said, it's just the better purchase in the long haul.

Also not sure what this 'ffxiv doesn't work well above 60fps' thing is? I aim for 100fps with my X34A and it's an absolute treat.

Don't sweat it about the ram, it's an easy upgrade down the line and with ram prices as they are currently, that's something that you're likely better off doing at a later date. Again, it's money better off spent on the GPU.

One luxury I'm amazed that no one else has mentioned tho: An SSD is literally the biggest single quality of life upgrade you can make to any PC, and they aren't expensive anymore. If you really aren't keen on doing any tinkering yourself, consider getting a build that's got one out of the box. You can thank me later.
