I originally had it on XBOX because my pc at the time was really old and could barely run Oblivion. I built a new pc and have never looked back. All i can say is make sure your parts are strong enough to run this game maxed! It looks so good on ultra with mods running. My only mistake with my build is I need a stronger processor. Looking at the i3 2100 or the i5 2500k, depends on my budget in the future.
But yeah its a whole new ball field and its kind of a learning curve but once you figure it out all is good. Especially with the mod forums and the pc forum, they can be so helpful. Just let them know what you have running and what your issue is.
