Best Value Lenovo?

I'm primarily looking for a good CPU and GPU, a good screen (500 nits preferably, I'm not knowledgeable on most of the other display specs), and good battery (AMD). I'm also looking for under $1200, and preferably with a payment plan. I want to be able to stream.

I was first looking at a Legion 5 Pro 3070ti before I got broke, then a 4070. But I hear the 4070 isn't a good enough upgrade from 3070ti or even 4060. I'm also not knowledgeable on the Slims.

My current computer is a 1060 and the CPU is even older, and The Finals playing like shit is kind of the last straw lol. I know that game and Path of Exile is CPU intensive though.
