According to videocardbenchmark.net your video card does not meet the minimum recommended specs, so you most likely wont even be able to run the game. If you really want to play Skyrim on PC you should think about investing in a new Video Card.
The rest of your PC should be good enough to run the game because the minimum CPU that you need to run Skyrim is a Core 2 Duo 2.0 GHz, which your's is better. Also the recommended amount of RAM for the game is 3GB which you have alot more than needed.
