Really need to know your exact processor to give a better answer. If you have HD2500 which is the same as HD2000 then the RV610 is slightly better. If you lucked into a Core i3-3225 with HD4000 then it is significantly better than RV610. Yes discrete would free up some memory but I doubt it's a significant issue for you. All in all I would say just stick with integrated or get a modern graphics card.
