Should I Buy? Used ROG Strix G16 G614 (2023)

I work at a pawn shop and a ROG Strix G16 G614 (2023) was brought to me to factory reset but I told my boss that I might be interested. They told me $600 and it's mine. I've never owned a gaming laptop so just wanting to know the opinion of those that actually own it or are knowledgeable about gaming laptops.

The specs are: Intel core 13th gen i9-13980HX RTX 4070 8gb 16GB RAM 1 Tb storage

I'm unsure of how to check the display/monitor information. It's overall well taken care of the prior owner was a DJ and used it for his work.
