If you guys have watched the interviews about crysis, you should know that computers that were high end 2-3 years ago, will work totally fine with crysis. They will optimize the game so that everyone should be able to play the game, and even at low graphics, it will still look amazing. remember, turning down the graphics, doesn't mean you cut out all the special things with crysis (leaves moving, clouds wich actually is clouds etc)..

imo i think you will be able to play it, yes, at decent framrate..
