With a WorldBench 6 real-world speed score of 132 points, the Arbico HD5750 XL is the fastest sub-£750 Windows 7 PC we've tested.
We're used to Arbico delivering top-class systems, and this month is no exception. With a WorldBench 6 real-world speed score of 132 points, the HD5750 XL is the fastest PC here - albeit by a rather narrow margin.
Another system built around Intel's brand-new Core i5 processor, the quad-core Arbico HD5750 XL is a challenger for the fastest dual-core PCs at this price point. And this applies even when they're not running multithreaded apps, which used to be the main advantage of opting for a quad-core system.
Windows 7 PCs will be available from 22 December 2009
This great performance is helped in part by the Arbico HD5750 XL's Gigabyte GA-P55M-UD2 motherboard which, despite being a budget model, offers a vast array of overclocking and voltage-tweaking options that can help you eke out every last bit of speed. The Gigabyte offers a pair of PCI Express x16 slots, while support for CrossFireX means you can add a second graphics card later.
In common with most of the PCs here, the Arbico HD5750 XL comes with 4GB of fast DDR3 memory and a 500GB hard drive. The system is housed in a smart Cooler Master Elite 333 case, with side-mounted USB ports and control switches. And it's great to see that Arbico has finally abandoned its usual 460W PSU in favour of a beefier 800W model.
However, this performance isn't enough to secure the Arbico HD5750 XL a place at the top of the charts. The 22in GNR display delivers a reasonably good picture, but it can't match the full-HD resolution of the BenQ model supplied with both Chillblast machines. Neither does it come with any external speakers.
The biggest drawback, however, is the Arbico HD5750 XL's reliance on an ATI Radeon HD 4870 graphics card rather than the faster HD 4890 model. The 4870 is still pretty nippy but, with the 4890 available in similarly priced systems, there's no reason to settle for anything less.
