All the systems in this month's chart use Intel's Core i7 920 quad-core processor, but large disparities in performance remain. While the CyberPower Gamer Infinity i7 Galaxy doesn't reach the stunning performance levels set by Chillblast and Arbico, a score of 128 points in WorldBench 6 is still very good.

The CyberPower Gamer Infinity i7 Galaxy lacks the high-performance Raid 0 sub-system of the top two PCs, instead providing a single 1TB hard drive. This is a straightforward, more reliable approach, but offers 500GB less storage.

Several high-quality components push up the CyberPower Gamer Infinity i7 Galaxy's price tag. For starters, it's housed in a superior Cooler Master Centurion case and fitted with a meaty 700W power supply. This provides plenty of juice to the HD 4870 X2 graphics card, which delivers some of the best framerates in the chart. If you're willing to pay the extra £150, this is an excellent gaming PC.

The MSI motherboard offers plenty of room for expansion and will happily support a second graphics card. There's also 6GB of RAM as standard, and it's easy to upgrade further with the CyberPower Gamer Infinity i7 Galaxy's trio of available memory slots.

The 21.6in Hanns-G display comes with a digital input and will be adequate for most users, although it looks a little small next to the 24in monsters elsewhere in the chart. Larger screens such as these provide 1,080p (full-HD) capability; the CyberPower Gamer Infinity i7 Galaxy doesn't have a Blu-ray drive either, so enjoying HD films would require several upgrades.
