I own the Samsung 49" powered by a 1070, it runs driving sims really well, albeit I am running sims from a few years ago (Raceroom Experience, Automobilista 1&2, Assetto Corsa). However I think if I tried say Microsoft Flightsim, Cyberpunk - it will struggle! Yes you can see more because of the resolution, I bought mine as I used to love triple screens for driving games, its a perfect replacement. In some cars you still have to glance right or left to view your furthest wingmirror (dependent on the car and how wide it is - or you can get around this and just change the FOV in game). Films or Netflix don't fill the screen, you will get borders.
I haven't tried The Witcher 3, Kingdom Come Deliverance, Red Dead Redemption which is next on the list, I think this is where the limitations of my PC will creep in so I'll have to accept that I need to reduce settings. I don't mind playing some games with borders (I play Quake 3 at 1600 x 1200). For sims which are a 4 years old - its amazing and works really well. It really depends on the games you intend to play, I also turn off all the artificial fancy stuff (blur, bloom etc) and AA (as the resolution is fine). For driving sims and shooters it is awesome. As
@pp111 mentions, I chanced my purchase because I rarely buy any latest games (until I upgrade) so I was not too worried if I had to reduce some detail.
On the whole, It was a pleasant surprise that it works really well (better than I anticipated) but you may want to play some demanding games and therefore, you might need to upgrade or reduce detail/resolution.
