You should find the Dell Alienware, XPS, Asus ROGs, Acer Predators and more with the 1070 GPU and better than 60Hz displays.
Since this is for gaming I'd even entertain the 17 inch models. There are a lot of models that fit this price range.
Let me comment about https://www.cnet.com/topics/laptops/best-laptops/gaming-laptops/ models.
My son has a Razor and it's slim build comes with a price. Not dollars but heat buildup and it will throttle. Not badly and if you put it on a cooling pad you have to really stress it to get it to throttle but not everyone knows this.
For me, HP is not an option as they bailed on warranty to a 3 month old model.
Asus is listed but you can find models at your price point. Just pick out a nice 1070 or 1060 based model.
The Acer Predator is there and I am on the 17 inch model. Would buy again.
MSI is not seen often but folk do like them,.
Digital Storm is to me a new player. I'd pass.
I've had Lenovo's and as long as Lenovo uses PWM and the LCD's flicker I'd steer clear.
The Dell Inspiron is a good value but for you, you have set the sights higher.

I would like a gaming laptop to mostly use at home to play Indie's or games like Rainbow Six Siege with my friends. I've done a bit of research on what I'm looking for but there are so many options I'm still unsure what laptop to buy. If anyone could help advise me or suggest any laptops that would help a lot. I want a decent sized laptop used almost exclusively for gaming (R6S, GTA and other shooters). Please suggest laptops under $2000. I'm looking for performance mostly! Thanks in advance!
