Many games (but not all) has those benchmark mode that allows you to see how much fps you can get. Then there is the programs like 3DMarks.

but then how can i know what setting suit my system best?

Is this for gaming?
Keep tweaking and tweaking the settings until you get the most optimal result. Try resorting to heavy games as it gives clearer result.

Usually high-end games will have fps tester. for instant, it will play a movie at your custom configuration. after that it will gives u the result in fps
