IGN's review of the PC version with some videos.http://pc.ign.com/articles/121/1212033p1.html
Here is one excerpt from the review that is good to know:
"As good as the visuals are in the Xbox 360 version of Skyrim, there are a few drawbacks. Even with the game installed, load times are lengthy and frequent. Every time you fast travel, every time you enter a building or town with a door, you'll need to sit through a load. You'll also experience framerate drops depending on how much happens to be onscreen. The PC crowd should be happy to hear that, assuming you've got a powerful machine, [the PC version of] The Elder Scrolls V looks far and away the best. The draw distance can be pushed way back, letting you see clear across enormous spaces, and you benefit from a higher visual quality throughout, as well as dramatically shortened load times, to the point where they barely exist at all."
