Eclipse's Fusion Crossfire i792R585 is a power-hungry Windows 7 desktop PC based on Intel’s Core i7 920 CPU and an HD 5850 graphics card.

Following a similar spec to the Best Buy Mesh, the Eclipse Fusion Crossfire i792R585 is also based on Intel's discontinued Core i7 920 CPU, combined with an ATI Radeon HD 5850 graphics card.

The Eclipse Fusion Crossfire i792R585 picked up 133 WorldBench 6 points, the lowest score here, but performance is still good; most users wouldn't notice the difference of a few points.

With 6GB of RAM fitted into the Biostar motherboard, three slots remain for future expansion. The Eclipse Fusion Crossfire i792R585 also offers support for CrossFireX, enabling to you to boost gaming performance with a second card.

A terabyte (1TB) of storage is provided with the Eclipse Fusion Crossfire i792R585 in a single drive. This doesn't offer the performance boost of our Best Buy machine's Raid 0 arrangement, but it's less prone to data loss.

The Eclipse Fusion Crossfire i792R585's Arial AI-01 system case is one of the most stylish and solidly built of the group. It looks expensive and comes with a pair of USB ports and audio jacks conveniently placed at the side of the case.

The 24in full-HD BenQ widescreen monitor is another excellent choice on Eclipse's part, delivering excellent image quality whether you're working, gaming or watching HD video. A Blu-ray drive would have been a welcome addition to complete the Fusion Crossfire i792R585's multimedia credentials, however.

Buying advice

Processor: Intel's Core i7 chip is taking this price bracket by storm. It's a match for the best dual-core systems and will outpace any previous-generation quad-core machine. However, Core i7 chips require more expensive DDR3 memory and a new motherboard design, so expect to make sacrifices elsewhere.

The latest Core i7 800-series processors use lower-cost motherboards and can compete with the lower end of the Core i7 900-series on performance.

Dual-core CPUs are still available, but the time has come to switch to the quad-core architectures.

Memory: Consider 4GB as a minimum. If you're buying a Core i7-based system, however, expect 3GB or 6GB of RAM (such machines install memory chips in threes). The Core i7 800-series and Core i5 chips install memory sticks in twos, however, making them excellent value for money.

A 64bit OS will take full advantage of your RAM, but check that your software and drivers will be supported. If you opt for more than 4GB, a 64bit OS is essential.

Storage: Anything less than 500GB is now considered a small amount of storage space. Many users will get by with 320GB but, with prices falling, it isn't impossible to find a terabyte at this price point.

Get a multiformat DVD writer that can write to a dual-layer format if you want to store 8.5GB on a single disc. Look for a minimum of eight-speed DVD+R DL. Try to get eight-speed DVD+RW.

At this price you may also find a drive that reads Blu-ray discs - note that it won't burn to Blu-ray, and DVD burning speeds will be slower.

Display: 22in or 24in flat-panels are the standard here. Many vendors supply budget screens in order to leave more room in the budget for other components, but it's worth spending a little more if you intend to work primarily with digital photos or video.

A screen with a response time of 8ms or less will minimise blur on fast-moving images. For image editing, contrast ratio and colour fidelity are more important.

A digital input can preserve picture quality, so think twice about displays that provide analogue inputs only.

If you're a movie fan, look for one of the new 16:9 format 22in-plus displays that offer full-HD playback. You may even be able to find a 24in model.

Graphics card: At this price point, the ATI Radeon HD 5850 is an almost unbeatable choice for gamers. It offers multiscreen support and supports DirectX 11.0.

You'll also find good deals on nVidia's GeForce GTX 260 (or even GTX 280). Look for souped-up versions with faster clock speeds or additional memory. nVidia cards offer some unique features, including support for 3D gaming with compatible monitors and glasses.

The GTX 260 and HD 5850 can be used in dual-card setups later but, to take advantage of this, your motherboard and power supply must be compatible.
Ready-made dual-card solutions are available but can be more expensive.

Power supply: The level of power you require will depend largely on the type of graphics card you expect to use. Look for at least a 500W unit at this price point, but consider 750W upwards if you have any thoughts of moving up to a dual card solution later. Overclocking will also demand a high-quality power supply.

Sound card and speakers: Onboard sound is no match for a sound card. Consider Creative's Audigy 4 or X-Fi range.

OUR VERDICT

We’ve placed the Eclipse Fusion Crossfire i792R585 and Mesh’s Ice 7 DX11 higher than the Core i7 860-based Chillblast and Arbico PCs because their higher-spec motherboards and triple-channel memory offer potentially higher performance. But the down side is that there’s less room in the budget for luxuries such as Blu-ray players and speaker sets.
