Its a good setup. You will be able to run Crysis 2 at moderate frames like maybe 25-30 or even 30-50 while MAXING out the game.
Since, its a laptop, I wouldn't expect much, but it would definitely be able to run Crysis 2.
Check these videos out, they are on GT 540M but there is a difference in the processors.
This laptop will surely play Crysis 2 at Medium specs. But you must buy a cooling pad to put beneath ure laptop as when playing games on any laptop for longs hours it will get hotter and hotter so plz i will recommend u to but a cooling pad. Great Playing with this superb game!
