Razer has been into laptop gaming for a long time. It is considered a premium brand. Lenovo jumped in a few years ago. They give a pretty good bang for the buck. I considered the y545 with a 1660ti card but wanted a 17.3" screen. Looked at the Lenovo y740 or 745 and it was good price point for a better card. What I didn't like was its matte lifeless screen. I game but do artwork and graphics. Alienware is banned from my house forever and overpriced for the garbage parts they use. That means no more Dell too. I looked at Asus, MSI and Acer. Not a fan of HP.
A 17.3" laptop has more room for bigger heat pipes and I don't play the newest games now. Ended up with a thin, vibrant GE75 Raider MSI, 16gb ram, 2060 full sized card, I7-9750 chip,500gb ssd and 1tb hard drive. It has a nice keyboard too. Battery life sucks but is usual in a gaming laptop and it is really a desktop replacement for me until I have another desktop built to replace my maxed out Alienware giant paper weight. Then this will be in my art studio or bed. Hating all the Windows 10 machinations but love my new laptop. I was surprised to get it for $1200. The 2070 card was overkill so I saved some money.
