What is this pc like for streaming Fortnite and similar games?
If you want to use the PC for photos, etc., there's probably not enough space.
Do you mean with streaming, streaman a la Google Stadia or live broadcast like Twitch? In both cases, the computing power is outsourced and you need quite little power, just good internet…
Streaming on Twitch and Co.
Looks very reasonable. If you have a lot of games, you may have to buy an SSD.
Aso, you mean streaming yourself?
Looks stable. Would buy a hard drive for pictures and video
The system is good and well thought out. I have an almost similar system, only that I have a 5ooGB m.2 and a 2T SSD and another GPU.
Counter question: Do you need a 37oox? A 36oo is enough for your needs. I have a 37oox because I also need it professionally.
Is the graphics card good or should I install an Nvidia?
This is quite ok and most teething troubles are already behind.
