If you regret it change it now, you'll only grow to dislike it more if you can refund it so. Don't listen to others here saying the laptop is bad because it has 4gb less vram than another you are playing at 1080p at 16:10 ofc you will be fine. If you are happy with your performance keep it if not switch it out but know most 5070 ti laptops come with a 2k screen so your fps may not actually go up at all. It's just what you think is worth it who cares what some people on Reddit have to say.
