I have a question. My specs are:

Intel Core I7 950 3.0 GHZ
EVGA Nvidia GTX 570 superclocked
OCZ 4 GB PC 1600 RAM

Should these specs be enough to get a solid 60 FPS out of vanilla oblivion with the 4 GB mod at 1920x1200 on ultra or high? I ask because I am not seeing it and I want to know if its something with my system?
