Also based on the Core i7 920, CyberPower's Gamer Infinity i7 Galaxy is a good performer, if not quite as fast as the Arbico or Chillblast.

Housed in a striking black-and-silver NZXT case, the CyberPower Gamer Infinity i7 Galaxy will appeal to gamers without appearing too garish for general use. The external drive bays are hidden behind a magnetic-lock door with transparent smoked-acrylic panels. The case also incorporates a pair of quiet 120mm cooling fans that use a screwless design for easy access and installation of components.

An ATI Radeon HD 4870 X2 graphics card provides excellent gaming performance, reaching comparable levels to the similarly equipped Chillblast. However, if it's gaming performance you're after, Mesh's Matrix 295 HD is faster and costs less than the CyberPower Gamer Infinity i7 Galaxy.

A 24in Optiquest monitor is provided with the CyberPower Gamer Infinity i7 Galaxy, which bears more than a passing resemblance to similar models we've reviewed from Digimate.

The CyberPower Gamer Infinity i7 Galaxy is alone in its inclusion of a sound card, and its Creative X-Fi XtremeAudio can potentially improve audio quality - although it could be argued that the onboard audio found on newer motherboards offers sufficient quality for most of us. A set of Creative T6100 speakers completes the deal with a full surround-sound system - a good complement to the Blu-ray drive and HD-capable display.

The CyberPower Gamer Infinity i7 Galaxy's Asus P6T motherboard is feature-rich, while the 780W Hiper power supply offers plenty of potential for upgrades.
