Budget Laptop that will run Rome 2: Total War?

I'm looking for a laptop that costs around £400, I don't want to stray into the £500 territory but if it's necessary then I guess I have to. I'm not looking to run it at Ultra and I'm satisfied with a Low to Medium graphical setting for the game. I'm also interested in playing WoW and possibly Minecraft on it but I don't see that being a problem due to neither being that graphically demanding.

I don't know much about PC's and PC gaming so please speak as simply as possible, I've typically just inherited old macs from my parents and make do with that.

I've never played the game and I don't know what kind of spec would be like the "average specs" for the game, but i would look for a PC with an Nvidia GPU ( graphics processing unit), A dual core or quad core processor running around 2 GHz, and a memory of at least 4 GB ( i would go to 6)
