If you have the 2011 MBP with AMD 6750m graphics card, you should be just fine running Skyrim or most other 2010-2011 games at 1440x900, 1600x900 or 1920x1080. I don't think the 6750m would be powerful enough to run games at 2560x1600, however, if you use an external monitor.
EDIT: I see it is the 13-inch MPB, which uses the Intel HD3000 graphics. Native resolution is only 1280x800, but I'm still not sure whether you would be able to run Skyrim with the HD 3000 GPU.
