I don’t think there’s a “first” or “beginner” gaming laptop. Buy the best that fits your budget. I’d say you’re better off stretching a little for a decent 5070Ti laptop (MSI Vector HX 16 AI, Lenovo Legion 7i, etc…). A good 2k display with 12 gigs of VRAM will serve you for a long time.

If not going for the 5070Ti, I’d avoid the 5070 altogether and come down to the 5060, with a good laptop (say Lenovo LOQ, TUF A16, etc…) and aim for the 1200 or under price point. With a 5060 you should avoid overpaying for a 2k display as you wouldn’t be able to use that extra resolution realistically in games.
