I haven't done an MBA myself, but I think its worth definately ensuring that the MBA is targeted towards your needs and career aspirations (IT sector), and from a high reputed university. You also need to ensure that the degree will be worth something in the next few years, as it is an expensive course which is going to mean sacrifices, unless you have a sponsor.
Many universities offer MBA programmes, and quality obviously varies between them. In my opinion, you are best off consulting the rankings to decide from the top list of schools (LBS, Cambridge, Oxford, LUMS, MBS, Warwick, Cranfield, City).(http://rankings.ft.com/global-mba-rankings)
Good luck!
