Thought Evesham's Zieo NX600-HD had enough raw power for you? Think again. It's just been superseded by the almighty Zieo NX600-HDX.That's X for Xtreme – or Intel's X7900 Xtreme processor to be precise, with 2.8GHz of throbbing Core2Duo processing power under its belt providing the most skid-mark-inducing experience of any of Intel's mobile chips.Working in tandem with the CPU is a giant 4GB of RAM and a speedy 200GB 7200rpm hard drive. Chuck in 512MB of NVIDIA GeForce 8700M GT graphics for the 17in display to feast on and you've got one seriously capable machine.It's out now from a starting block price of (gulp) £1900. Better start saving.Essentials Evesham Zieo NX600-HDX Price: £1900 On sale: Now Contact: Evesham Related stories: Gadget of the Day – Evesham Zieo NX600-HD Evesham lappy replaces the desktop replacement
