no-it simply doesn't matter how powerful pc's are as exclusive optimised AAA games with high graphics does not exist for this platform to show its real power.PC games simply don't have the budget to show the power
You will only get next gen console games with higher resolution and some more frames=the difference won't be huge.
As the next gen will be graphically on a high level and pretty close to cgi-movies(thats the top of the tops) it would not even matter if the pc is 20x more powerfull as high level graphics as there is not so much room to improve graphics.
maybe in 10 years when voxel engines combined with ray tracing will occure there will be a significant jump in graphics but until then the improvement in graphics will be pretty slow.
