January Build, £1000 - £1200

[CleverBalls]

Hey guys, what I'm really looking in this build is for a build that will last for at least a year on 1440p and hopefully then with an SLI upgrade will be available for 4k play around December next year.

I do not need the following;

Monitor
Case
Peripherals
Hard Drive
RAM

Thanks guys! I hope you all have a great new year!

Is the http://www.overclockers.co.uk/showproduct.php?prodid=GX-003-GX&groupid=701&catid=1914&subcat=1812 not a superior GPU? Would I require 850w to power two of these cards?
