How will programming, MIS, IT or comsci boost your finance or accounting career?

As we all know, MIS is complementary to finance or accounting. Anyone who has experienced tangibly benefiting from taking some programming or MIS lessons? I am interested in taking some of these classes, maybe even aim for a diploma in comsci or IT. But will it be practical to pursue a diploma or a degree on computing when you still want to stay in accounting, finance or IB, not totally shift to programming or pure IT job? Btw, for those who have been into this fields, how does comsci differ from IT?
