Budget (including currency): Between 1000€ and 1600€ (a little bit more will be okay.)
Country: Germany
Games, programs or workloads that it will be used for: I will use the PC for gaming, streaming and a bit Adobe Creative Cloud (Photoshop, Premiere Pro and Lightroom).
Other details:
I want to use an Intel CPU and an Nvidia graphics card. I know that AMD CPU's and GPU's are better in some perspectives, but I have so much good experience with Intel and Nvidia.
The PC will be standing on top of my desk. So it will be a bit like a design object so it must have RGB and because I love colorful lights.
Maybe in the future I want upgrade my monitors to 4K displays and 144Hz.
