What I meant was I get that these images show greater quality. However if these were simply screen shot from the operating system, I'm guessing the images would be in the 4k resolution and it wouldn't look the same in the monitor. Isn't this the case? Shouldn't someone use a dslr on their monitors to capture an accurate depiction?
I think, any modern cpu from this era probably won't bottleneck GPU's to an extent that will be noticeable. Sure, it will be slower than a i7 but unless the game you are playing is very intensive on the CPU, it should be fine.
