Buying an Alienware Laptop: is it good? Need advice

[SMWHackedHACK]

I want to buy an Alienware laptop. I will mostly play Galaxy, Sunshine, Kart, Melee and Brawl.

So these are the specs:
i7-7820HK (Quad-Core, 8MB Cache, Overclocking up to 4.4GHz)
32GB DDR4 at 2400 MHz (2x16GB)
NVIDIA GTX 1080
2560x1440
256GB PCIe SSD
1TB 7200 RPM SATA 6Gb/s

...on 1080p, is it good to run these games?

If it's bad or something, can you recommend me another laptop?
Thank you.

That should work very well.

That should work very well.

If it doesn't throttle the CPU under full load...
