I've been looking to purchase a new laptop for a while now, as the one I have is getting pretty slow and the parts in it are ancient! I'm hoping to sell it to someone in the family, but I've been trying to find a new one with half decent parts for about £400.
You will not get a decent gaming laptop for £400 I'm afraid to say. I have no idea what specs you need for total war but I know a friend had to upgrade his graphics card in his desktop to play it. But I may well be wrong on this.
I have just bought a small netbook from John Lewis with the 2 year warranty and it was the fact that no one in curry's or Comet or PC World seem to be able to answer any reasonable question I put to their sales staff about various laptops I was interested in.
