You won't find a decent gaming laptop for that price.
Youtube videos cannot be taken to absolution - people will tweak/hack setups to make it look that way, and some are just flat out lying.
Benchmarks also do not reflect real world performance. They should be used as a reference, as in game performance will likely be lower.
It's pretty good for older games, but newer ones? The gpu is horrible.
For PUBG, the cpu itself is decent, but again, the gpu is horrible. It doesn't even meet the minimum required gpu for the game, which is either GTX 960, or Radeon R7 370.
