u can get reports of any framerate... 60, 120, 234 fps... but ur limited to how many frames a second ur monitor can actually handle. this is where hz come in. a 60hz monitor refreshes the screen 60 times a second. 120hz monitor refreshes ur screen 120 times a second, etc... there r even 240hz monitors although they are very rare, expensive, and overkill. this means that gamers are limited to either 60fps or 120fps despite what their video card can push. so when u see someone bragging that their video card runs a game an average of 328fps on max settings, u kno the reality is that they can only experience at most 120 of that in almost every case (actually most gamers game on 60hz monitors, so anything above 60fps is completely wasted).

its also dependent on ur video card. my ultrabooks video card cud only run my 120hz monitor @ 60hz, therefor i was stuck @ 60 frames per second even tho my ultrabook averaged about 90 to 100 fps on CSS.

wen i built my gaming rig i specifically did research and bought a video card that can run my monitor @ 120hz. u also need a special dual link DVI cable to run @ 120hz (aka 120fps).

now i average about 190fps with this video card in CSS with a 120hz monitor: 70 frames of that will never reach my eyeballs.
