Sorry, but that is a miserably outdated chipset, and i highly doubt you will be able to get more than 15 fps with it. It will be a terrible experience and will ruin the awesome world of Skyrim
. You should consider buying a dedicated GPU. However, I might be wrong, so please double check and go to www.systemrequirementslab.com and see if your computer can run it. Also, do a google search, because we don't want our amazing forums to get polluted with questions that have already been answered years before. ANyway, hope I helped and best of luck!
