Although we tested it at stock speeds, the CyberPower Infinity Crossfire HD is usually sold overclocked to 3.6GHz. The Core 2 Duo E8400 can handle this quite easily, thanks partly to this system’s huge processor cooler, usually reserved for quad-core chips.

In any case, the CyberPower Infinity Crossfire HD was able to beat the rest of the field even when operating at 3.2GHz, turning in an impressive WorldBench 6 speed score of 127.

The CyberPower Infinity Crossfire HD's graphics performance was also excellent. In essence, the Sapphire ATI Radeon HD 3870 X2 places two graphics cards on a single board, providing the performance boost of a twin-card system without the extra space and power requirements.

Our review system was shipped with a 64bit edition of Windows Vista Home Premium, which enables the CyberPower Infinity Crossfire HD to take full advantage of the 4GB of installed memory. This has been supplied in two sticks, leaving two empty slots for even more memory.

It may be the smallest flat-panel in the chart, but the CyberPower Infinity Crossfire HD's 21.6in Hanns-G HG216DP monitor is deservedly popular. It features both VGA and high-definition multimedia interface (HDMI) inputs, and gives solid image performance.
