Art jimmerson vs phenom belfort

[ImmigrantMentality]

Art was a legit boxer but never got to showcase his skills. Vitor came a little later and was a black belt under Gracie but also showed the first real high level boxing skill in the ufc. What would have happened if these two would have been matched up against each other in the early ufc days? Would vitor have just taken art down and used his superior grappling or would he have tried to stand and bang with a pro boxer? Who would have won in that case?
