i Like the idea of a high quality monitor but i cant in could faith tell him to buy a $600 monitor and a $300 gpu. so... I will be overclocking his pc. and im thinking 16gb ram and an ssd would be nice. so what do u thing of going with an i7-4xxxK http://pcpartpicker.com/p/gDBRdC

You can run 4k reasonably well on a 390, this is with a 390x, so bit lower frame rates and power consumption, but most of the bigger games you can run at medium no problem, 4k is going to great for any space sim

Plus you can always throw in a 2nd 390 down the road with a slightly higher end PSU 850W or above and do 4k very well without spending a ton of money on a single high end GPU.
If he's just gaming 16gbs of RAM is a bit much, spend the money on a larger SSD

But it'd be my advise that you invest in a great display now, as in a year or so you're going to get better performance per dollar on a GPU, and you'll already have a 4k capable display, this one with the addition of free-sync

And if a game is really having trouble at 4k, then you can just run it at 1440p, and it'll be just like a normal 27" 1440p panel, but most games be fairly playable at 4k with lower settings
