It really depends on what you are trying to accomplish, and how electronics laden your room is. It might need more than those two circuits. Installing more outlets than the minimum, in areas where there will be a high concentration of electronics is good - and you might want to consider surge suppressed outlets, since adding a plug-in strip could be hard to hide. A flat panel on the wall might call for an outlet higher on the wall so you don't need to see the cord dangling down. Some people have their computer and printer in there. Some laser printer's heaters can have a pretty big draw, the newer ones are better than the older ones, that cycles on and off and can cause lights to dim. You might want that on its own circuit altogether. Add a big surround system and big flat panel display, a minifridge so you don't have to go to the kitchen for your beer, etc., and it can get quite involved. Add a big aquarium, you might want that on a dedicated circuit. So, while code (I don't think) requires more than one, two is not unreasonable, and even more could be called for. How you separate them is open for discussion.
