KitGuru review a range of gaming systems every month, from penny pinching £500 builds to wallet sapping £3,000 beasts. Today we take a look at one of the latest high end systems from etailer OverclockersUK (http://www.overclockers.co.uk/) . This £4,000 monster features a watercooled, overclocked Core i7 4770k, an Asus Z87 Extreme motherboard, 16GB of fast DDR3 memory and not one, but two AMD R9 295X2 graphics cards running in Quad Crossfire. If you are in the market for a new Ultra HD 4K monitor is this the gaming system you should be shortlisting?
