Alright so here's the deal. Will there be a noticeable difference between 4k and 1080p gaming on a 17 or 18 inch screen? Both would be at ultra settings. I don't wish to discuss GPU or CPU or the capabilities and so on, I am already well aware of all those things. I just want to know if it is worth the money for the upgraded display (you may as well think to yourself that it will have the exact same fps if that helps the comparison). Thanks all.
