Upgrading laptop - GT72 v GT80

Hello all,

I am looking to upgrade from my GT70 to a new laptop for gaming. I was hoping to get a 4k or near 4k gaming laptop but I wasn't able to find any that had the power that these two had. The linksfor the two I was looking at are below, these are the maxed out versions of each I believe.
