Do you think a computational math student should go to student seminars about pure math?

I am a first year graduate student with thesis topic on computational math, in particular inverse problem. Based on what I know, this area requires a solid background of functional analysis and numerical PDE.

Currently I am wondering what kinds of seminars I should attend. My department have weekly student seminars on analysis and theoretical PDE. Basically students presenting their work/research output to their supervisor. As this post and the great mathematician Terence Tao suggested, attending talks and conferences in different areas is beneficial. Hence I will try to attend other numercial analysis groups' seminars. But I was wondering whether it's helpful for me to attend those pure math seminars about analysis or PDE.

Though I found those seminars are interesting, my main concern is that being lack of suitable background, I may only be able to understand a small part of the seminar (a PHD student working on theoretical PDE once told me he can't understand his group-mates' seminar until his third year). The other concern is I will have less time for my own research . So in your opinion, what kinds of seminars I should attend? Shall I attend seminars in other departments (say physics or engineering) regularly?
