Can you gamble on it well?

Mainly wants to do some office things with it and occasionally play gta COD or Fortnite. Would that be enough for that?

No. It's just enough for Minecraft. More is not possible

No, only Minecraft could go

With COD, Fortnite and GTA it won't work. If then the old GTA parts and Minecraft.

Not really because the PC doesn't have a graphics card. And 8gb RAM is actually too little

Don't take it badly or even badly is just a little tip😉

It's a great system for Office. Games only run smoothly on low settings. If that's enough for you, then okay.
