This is tough to answer to be honest. Your workload for your major, work commitments and what type of club you want to join will all determine the answer here.
However, my suggestion is for you to join a club if you will enjoy the time off from work/school by being involved in it (or to meet new people which will keep you happy/sane). I would also recommend seeking leadership positions as these will help you land internships/full time positions later and develop you personally/professionally.
If you find that the time commitments are too great, consider quitting it, it is very common. We make trade-offs all the time, but I think smartly balancing your work/school commitments with social or community based involvement will add something for your soul which is sometimes more important.
