as Yang Ye said don`t run gromacs simulations on laptops, the laptop will die 
soon ...
atm buy intel centrino duo for laptops, its faster than amd and does not 
consume so much power. For analyising your simulation the harddiscs are the 
limited factor so you need a fast raid system.

Normally you do your md simulation on a cluster and programming and comparing 
of the results on your own pc.
