Which version of Mudbox do you have? A quick look at Autodesk's website revealed that the 2013 edition requires an nVidia Quadro series card or AMD FirePro series card, while the 2012 edition can be run with "regular consumer" cards (nVidia GeForce and AMD Radeon HD).
Blender has a Sculpt Mode and it is free, so I suggest giving it a try.
