I had an issue with the laptop hard resetting every now and again when I got it but a Bios update appears to have cleared things up. I've owned a lot of laptops in my time and its up there with the best of them. The CPU isn't as good as I'd like (yet still no slouch) but the battery life when not gaming is fantastic, 8-9 hours on light tasks so its a fair trade off. I travel a lot for work so portability is a big factor for me and its unbelievable just how good it is for such a small package. Has LM on the CPU so temps are under 90 during heavy gaming.
I have the 5080 variant but that's over kill, its not much better than the model you are looking at. The 5070ti its the one to go for for sure.
If you are gaming with it on it on the TV then you
will hear the fans, think PS4 pro loud and you get the idea, just something to consider. Same goes for any gaming laptop going full pelt though.
Like another poster said, remove armoury crate and install
GHelper Its free and super lightweight, great bit of software. AC is trash.
It also doubles as a great "work" laptop as well.
That said if you are only gaming at home with it I really would think about getting a Mini-itx to stick behind your TV. You'll get a lot more bang for you buck.
I have one of these at home and its great.
