We had high hopes for CyberPower's Ultra 6 Core Silent Edition, which combined the latest eight-core AMD FX 8120 CPU with an impressive case, excellent build quality and decent peripherals.

The minimalist design of the Cooler Master Silent RC-551-KKN1 case exudes quality. You can immediately tell that it's a premium housing. Behind a hinged front door, removable dust filters and built-in sound-damping materials line the case.

An Asetek closed-loop liquid cooling module provides further noise relief, plus efficient cooling. The CyberPower is very quiet, which is a major draw for use in a home environment.

Unfortunately, our hopes for great performance were dashed when we were unable to run any of our benchmarks. The CyberPower Ultra 8 Core consistently failed one of the sub-tests of WorldBench 6, while Crysis wouldn't run at all. We reinstalled Windows and checked for the latest drivers, all to no avail. We tried a different processor, the six-core AMD FX 6100, but with the same result. Thinking that there may have been a compatibility issue with AMD's latest CPU architecture we then tried a six-core AMD Phenom II 1055T. The system then worked flawlessly with this older processor installed, so it's this configuration we have tested and reviewed here.

With the replacement chip installed, we recorded a WorldBench 6 score of 123 points. We estimate that this result is about seven points slower than what would have been achieved with the original processor had it completed the tests. It's also considerably slower than competing systems based on Intel processors.

An Asus M5A97 motherboard offers many premium features, including automatic overclocking and software control over fans and clock speeds within Windows. Unfortunately, the Phenom II 1055T doesn't feature the unlocked multiplier of the FX 8120 CPU and is less able to take advantage of the overclocking features.

An AMD Radeon HD 6750 graphics card is fitted, which provides less power than the Chillblast's HD 6870 and Eclipse's GTX 560 Ti.

23.6in HKC 2412 monitor, Logitech stereo speakers (with a subwoofer) and a Lite-On Blu-ray combo drive deliver a comprehensive multimedia experience. We were also impressed with the built-in Wi-Fi connectivity and Logitech wireless peripherals.

OUR VERDICT

An expensive, but impressively built PC featuring superb build quality, quiet operation, a built-in card reader and Wi-Fi. Compatibility issues prevented it from reaching its full potential.
