I hate to say it, but I don't think you need a €3000 computer.
$3000 is a gaming PC, or CAD PC. Unless you're a professional streamer or a CAD designer, you don't need it. You can get a decent computer for 1/2-1/3 of that price.
At the same time, it's okay to buy things you don't need, if you can afford them. But you have to decide if you should.
