PowerSpec G765 with 5080 GPU connected to LCD TV

Hey everyone, seeking your advice...

We have an LG - 86” Class UP8770 LCD TV from back in 2021 where we play Xbox, PS5, Switch 2, and Steam Machine - big physical game collector so have a large console game library...

We recently got a Legion Go 2 Z2E, which stirred something in me regarding PC gaming as I used to build my own gaming PCs as a kid in the late 90s, and my son is 14 and really into electronics, tinkering, and would love if we had a PC...

I was looking at getting PowerSpec G765 Gaming PC...

What are your thoughts?

It would be connected to the TV to basically play steam games and for my son to tinker around with - I am guessing it is kinda of redundant do to our gaming consoles but it would be cool to have some gaming PC in the house....

Is the PC a good build, and will the TV be a problem (e.g., will it be a bottleneck or suffer performance issue if receiving input from a 5080 GPU as it is not a gaming monitor)?

Thanks for the advice - hoping to make a decision in the next few days...
