I think this question is a bit difficult to say. There are no special restrictions. Personally, I think it is more appropriate to buy it in the first half of my freshman year or the first half of my sophomore year, because computer major is a very subdivided major, including graphic design, data, programming and other disciplines. You don't have to study all of them, but one course is specialized. You can sit down and have your own professional understanding in the first half of the semester. I mainly focus on that and offer those courses, so there will be deviations in buying a computer, such as learning plane image processing. Your computer has better display equipment and higher requirements for the processor, so this is my personal suggestion.
