Should I get the minimal client?

I just had my monthly file corruption and had to uninstall and reinstall the game, and was wondering if this time I should get the minimal client. It performs alright with full client (about 30fps on ultralow graphics) but the main problem is storage. The full client leaves me with around 3 to 5 gigabytes of storage, which causes problems when I want to record videos or try different games. Is there much of a difference between minimal and full client (on ultralow) in terms of graphics or is it completely unplayable?
