what should I do?（どうするべき？）

I'm wondering if I should buy a new computer. I would like to start video editing, but I can't do it on my current PC because of its poor specs. However, it's only been two years since I bought my current PC, so I think it's a waste of money. I would like to think about it for about two weeks to see if I really need it.

新しいパソコンを買うか迷っています。動画編集を始めたいのですが、今のPCではスペックが悪くいため作業ができません。しかし今のPCは買ってから二年しか経っていないので、もったいないかなとも思います。二週間ほど本当に必要かどうかを考えたいと思います。
