GTX 660 Ti gives a pitiful 94 Mh/s.

Hard to go on without more information. Are you sure you are providing enough power to the boxes? Could try connecting each one to a separate outlet (preferably with a surge protector in between). See if that helps.

You may want to find a nerdy/geeky friend to open the boxes and make sure you have the correct parts and that they are in good condition.

Could still be profitable if you find someone to cover your electricity costs - employer/workplace, solar power, etc. At 1.5 Gh, you should still make a decent return on investment though over next year or two, right?
