if you use something like xfire, it has an option to put fps in the corner...and depending on the game, there are in-game options too. Games like the call of duty series, you can type:
cg_drawfps 1 in the console, and it will display the fps. also tools like evga precision, will display gpu clockspeed and memory speed in the game
