Imho investing in a expensive high end gaming rig is just not smart, you'll never get your money's worth.
It's like owning a Ferrari and crying that the slower cars are holding back the development of faster highways.
You don't buy a Ferrari because you can go 300 kph on the highway, you just can't because no country's infrastructure is made to accommodate that, except maybe in those rich arabic oil states.
Game developers will mostly always target the largest group of potential buyers, that is not the few percent with a monster gaming pc.
The thought that console would hold back pc is an illusion, if console needs less presure on the graphics then the devs will just lower the graphics for console without touching those for pc.
Isn't the game's size bigger on pc? on Xbox One it's 15.3 GB, if it's bigger on pc then a large portion of that difference is probably because of higher resolution textures.
