battlefield is NOT compatible with the 9250. I have that gfx card. Never worked. I even checked for solutions, called the company, said it wasnt compatible.
My friend plays bf2 on a fx5500. The highest fps he gets is 30, and thats when nothing is happening, or he is flying in a chopper or plane. He usually gets about 18-20 fps. I dont think its really worth it in those conditions really.
