Building a gaming computer £1000-1500

[tomohawk]

So i want to build a pretty future proof gaming rig, if you could build me a really solid one for £1000 that would run most games for the next year that would be great but i am willing to go up to £1500 if necessary. Any help would be greatly appreciated.
P.S i would like to build it my self so i only need to know the components and prices Tom

Do you need Monitor/KB/Mouse/OS?

Do you need Monitor/KB/Mouse/OS?

The only thing i really require is OS but i would love to have a double monitor set up so if you could recommend a high quality monitor for a decent price as well that would be great.

This was already in the cart from a previous build for another member. Bout as future proof as you can get with the budget. Leaves you plenty of wiggle room for a case you might like better and a monitor.
