For self-actualization + future gift for brother

Hello, my name is Arthur. I am a student, I study in the field of information technology, and in my spare time I do drawing and 3D modeling. However, my old computer does not allow me to do all this at home, and for this I need a good computer. Later, when I finish my studies, I will give this computer to my brother for his birthday. So please help. Thank you in advance.
