Thoughts on this for a traveling, gaming laptop?

I would like to know if the specs are worth the price. If it's overpriced by no more than $300, that's fine, anymore than that and I will keep shopping.

I don't know anything about the 4080, I know everyone says the 4090 is top tier, and I have a 4070 in my desktop, and I LOVE it, but never hear anyone mention the 4080.
