Good WoW build for under £500?

[Deleted]

I am new to all this PC stuff and ATM i use this pretty old laptop that sometimes only has around 5 fps and tops off at 17 fps at its best times, I am thinking about buying a computer that will allow me to make use of pc gaming for a good price. Id really like a very fast computer (no lag) and decent graphics.
thanks in advance.
I wouldn't only use it for WoW but would also buy Battlefield and Skyrim etc.

Fill out the sticky in this section. In particular we don't know if you need peripherals and an operating system.

This would handle WoW at medium settings for 60FPS+, will dip in raids a bit most likely.
You could play BF and Skyrim on low-low/medium. Mouse and keyboard would be like 20 pounds more or something.
