DF pointed out that the 300Hz display doesn't have a 120, or 144Hz mode, nor Gsync. And the laptop isn't powerful enough to play anything at 300fps, even CS:GO. And that was the best they could say in a sponsored video where they were paid to like it.
Its mismatched so as to be pointless.
So you're basically paying an extra $1000 for a mediocre 60hz display. Plus the GPU is likely to be obsolete in a month or 2.
BUYER BEWARE - Battery bloat common after 1yr of use. Razer will also not honor warranty or extended warranty if you upgrade SSD or RAM. Terrible Customer Support. Get a Dell instead. Trust me, they are holding my 1yr old Razer 15" Advanced hostage demanding I pay $400 for repairs and refuse to honor my $379 Razer Elite Care.
