Whats the best (and cheapest) PC configurator for gaming pc's?

How about me giving you the best build for your budget? Tell me your budget and I will give you a great balanced build. (You will have to build the computer)

I don't recommend configurators like Cyberpower or iBuyPower because you will pay a much more higher price, and often the parts choice is unbalanced.
 

£550-650
