Eclipse Cosmos i726n57 review

£999 inc VAT

Manufacturer: Eclipse

Our Rating: We rate this 4 out of 5

It doesn’t immediately stand out as an impressive machine, but a premium motherboard provides the Eclipse Cosmos i726n57 with several unique features and bags of overclocking potential.

£1,000 PC buying advice

Processor: Intel’s second-gen Core i5 and i7 CPUs are the only serious contenders at this price. These ‘Sandy Bridge’ chips are much faster and use less power than their predecessors.

The 3.4GHz Core i7-2600K is the fastest available, with its ‘K’ designation denoting an unlocked multiplier. K-series CPUs are designed for overclocking, but demand a compatible motherboard.

At 3.3GHz, the Core i5-2500K offers a slightly lower specification. Unlike the Core i7, it has no support for hyperthreading and has 6MB rather than 8MB of level-three cache.

Motherboard: K-series chips require a motherboard that supports overclocking. These boards cost a little more, but a good version will do the hard work for you, providing a significant speed boost without any specialist knowledge.

Never pair a K-series CPU with a motherboard based on the H67 chipset – these don’t support overclocking. If you want to overclock, you should also invest in a third-party CPU cooler.

A 64bit OS will take full advantage of your RAM, but check that your software and drivers will be supported.

Storage: With storage prices falling, expect 1TB. We’re even seeing systems with 2TB at this price. An SSD may be available, providing a noticeable improvement in bootup times and system responsiveness. Their price requires cutbacks elsewhere, however.

Paired with a Z68 chipset, an SSD can boost hard-drive performance using Intel’s Smart Response Technology.

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.

It’s not uncommon to find a DVD drive that also reads Blu-ray discs, but DVD-burning speeds will be slower. Look for separate Blu-ray and DVD drives for the fastest performance.

Flat-panel: 24in flat-panels are standard at this price. Many vendors supply cheap screens to leave more cash for other components, but it’s worth spending more on a display if you intend to work with digital photos or video.

All twisted-nematic (TN) screens now have a response time of 8ms or less to minimise blur on fast-moving images. For image editing, contrast ratio and colour fidelity are more important – look for better in-pane switching (IPS) tech here.

An LED backlight doesn’t guarantee a superior display, but such models are often slimmer and more stylish. A digital input preserves picture quality.

Graphics card: At this price, the ATI Radeon HD 6990 is an excellent choice for gamers. It offers multi-screen and DirectX 11.0 support. nVidia’s GeForce GTX 560 Ti delivers similar performance, as well as support for 3D Vision.

You may find a GeForce GTX 570 at this price, which will give you even better gaming framerates.

Look for souped-up versions with faster clock speeds or additional memory.

Many graphics cards can be upgraded to dual-card setups. However, current motherboards have limited support for multiple graphics cards, so we advise you to buy the fastest single card you can.

Power supply: The level of power you require will depend on the graphics card you want to use. Look for at least a 500W unit or 750W-plus if you plan to add another card or overclock the CPU.
