What your PC can handle is an important point . Your AMD processor is OK and will handle the task . I would like to know about your video card , as this and RAM are the most important components when determining how well a flight sim will perform on your system . Click--->Start-->Run , and type dxdiag and click OK . Click the Display tab and get the name and type of your video card , then we can see about making suggestions .
Edit : With the MS simulator , you should be able to configure it for flying to and from non-controlled airports ( no air traffic control ). In fact , you should be able to select a configuration for a scenario to be as easy or as complicated as you wish . You could probably even configure it for simple " touch and goes ".
