Well, your computer can definitely handle it, just on some lower settings. I reccomend getting it on PC, The mods really bring the hilarity and Epicness into the game :D Although it is still epic without them, just not the same experience. So you played the part with the Greybeards? That was an average part. Basically just search for someone and they give you a reward. It was pretty close to the beggining of the game too, so it is pretty boring, Nothing special. There are many parts in Skyrim where the game really stands out, like some quests will change how you see the game.
For example, on one quest, you go into a possessed house with a man who asked you to come in with him to investigate,then furniture starts flying around, and next thing you know you're friend gets dragged into a different room, is trapped in a cage by a demon, and it wont let him out until you satisfy his needs. Or when you go into a different dimension, with a beautiful and strange, atmosphere, and there are many paths to take, but only one will lead you to an extremely special weapon.
If you find the regular quests bland and boring, just give the game some time, after you start leveling and becoming more powerful, it will be almost a totally different game. You just gotta find the hit points. I highly recomend it, even if its not on PC. It is one of the best gaming experiences ever. Hope I helped. Good luck.
