will i notice a big difference if i upgrade from my MOTU 828 (mk1) to an RME multiface (mk1)?

i produce electronic music and don't do much actual recording.

i can buy a used multiface for $400 however i will then need to purchase the expresscard ($600! new and i cant find it used anywhere) so the overall investment will be about a grand.

is the improvement in transparency noticeable enough to drop a grand?
