It doesn’t matter. The nvidia graphics cards are still better than the competition from amd.
Cpus, however, have begun to see a serious shift away from intel and towards amd.
The combination of the two is becoming pretty common unless you are an amd purist.
As a matter of fact, I built my brother a computer not long ago that has similar specs to these save that it has a 2080 in it. Thing has demolished every game he has thrown at it.
This is also sensible advice unless he needs it now. Those will be a decent step up over the current offerings.
So do I! I 
computers.
