no crysis doesnt require the x800(sort of a lie) . if you want any decent FPS on the lowest you need a 7600 GO for a laptop, im not sure what the equlivent of that is in ATI but its not x800 i had one like 3 years ago and its no where near good enough to play crysis .
what are there rest of the specs on the laptop. but it will play other games like BF2 and half life 2 well
