Hi first of all DO NOT BUY that Laptop. Anything by Fujitsu Siemens will not last long, i have bought two laptops made by them, and both broke down after a year.
Secondly you will not get a laptop for £400 that will run ANY games, especially Fear.
For your budget, i would get this
Very decent CPU and plent of ram and hard drive for that price. Only comes with vista basic though. You won't find much better than that for the price.
