The Predator Helios is the best bang for buck. It was at $1050 in amazon last time I checked. It has a gtx 1060 so it runs pretty much everything at high/ultra, 1080p, 60 fps. Building a desktop with those same parts will cost you basically the same, since gpus are super expensive due to cryptomining. You don't have to buy a keyboard, monitor or windows OS too. You can easily spend $200-$400 in those.
