I'm looking at the Alienware M15x with the 720Qm processor, the 820qm is +£410 extra (so unless there is a HUGE gain to be had it is out of my budget). 4GB DDR3 ram, for memory card have option of the 512mb GT240M or for +£100 the 1gb GTX260M which i am guessing is the better option.
Will this system be powerful enough? As i'm a little torn between getting this laptop or just getting a i7 920 desktop with the latest graphics card which would come to same price. But obviously then i can't carry it around, i tend to travel a little and would be nice to take the pc with me. I have a large monitor on my desk which i plan to plug the laptop into when at home.
