You basically need a whole new system. My laptop should be able to run Crysis, although I have never tried to. I have a Toshiba Qosmio X305 series, mine is an older model. The newer models have a much better CPU.
Intel Core 2 Duro T7350 @2.0Ghz
4MB of PC3-8500 RAM (1066mhz FSB)
GeForce 9700GTS with 512MB of RAM
