Your laptop can not easily be upgraded. Since it is a mobile platform that is probably custom build for samsung, i would not take a chance and upgrade to a cpu that is not one of the choices when you buy the laptop. The CPUs that are delivered with this are: Intel Core i3 350M, Intel Core i3 370M, Intel Core i3 380M, Intel Core i5 450M, Intel Pentium P6100 . All of these are mobile cpus. A regular cpu will not work with this. Remember also that changing the CPU will probably void your warranty.
