Thirty inches. 2,560 by 1,600 grid. Four million pixels. That was the gold standard in PC displays. But it's just been blown away. Welcome to the wonderful world of ultra-highdefi nition visuals. With this outrageous £3,000 flatscreen, Asus is giving us our first taste of 4K resolutions. It might just be the next big thing in PC graphics. Can it possibly live up to the hype? Let's not get ahead of ourselves, here. Regular PCFers among you will know we've been a bit down on high-end PC hardware in the past. On the CPU side, for instance, Intel's been sandbagging on an epic scale. Recently, we've had the new Core i7-4960X - such a spectacularly incremental step forward, it's a bit like adding a seat to a single tube carriage on the Northern Line and then firing out a triumphant press release claiming increases in national public transport capacity. What a crock. Then there's graphics. AMD and Nvidia have at least been keeping each other honest on the performance side.
