To be honest, when I got frostfire bolt I just randomly used that and fireball to keep things interesting - I hate using the same spell over and over again. But that's just me. Fireball = More damage = mobs dead quicker = faster levelling / dungeons completed faster, so if that is what you are looking for yes, use fireball =]
