Simple fact - the PS3 and Xbox aren't set up in the same way as a PC. If they were, then you'd take them back instantly as they are useless. So, in truth, the PS3 and Xbox aren't not able to run the full game. True, they are running hardware that was desiged 6 years ago, but, like for like, a PC with the same specs as a console couldn't work.
 * "Lack of RAM" The PS3 and Xbox store ALL the data, except save data and update data, on their respective game discs, meaning they don't need as much RAM as a computer.
 * CPU - Simple - Consoles at a time only have one or two functions to process, hence the lower clock speed and processing rate. PCs have tonnes of stuff to process. Try looking at the processes tab on Task Manager when you aren't doing anything.
