Left 4 Dead 2

Developer: Valve Software

From our Left 4 Dead 2 review:
'Not only does Left 4 Dead 2 provide a chance to test your skills against a whole host of new enemies and using a slew of new equipments, it also lets you play with the new modes and maps created by Valve – and the worst levels created by Valve are still twice as good as the best created by amateur map-makers.'

Power Consumption

For the power consumption tests we aim to gauge real-world power draw. The power draw is measured via a power meter at the wall, so the numbers below represent the total system power draw from the mains, not the power consumption of a CPU itself. Measuring the power draw of any individual component in a PC is tricky to impossible to achieve. We used Prime95 to fully load the CPU.

Idle Power Consumption

For this test, we leave the PC doing nothing but displaying the Windows 7 desktop (with Aero enabled) for a few minutes and record the wattage drawn from the wall via a power meter.

Load Power Consumption

To generate a realistic load power consumption figure we load the CPU using Prime95's small FFT test, which mimics 100 percent load across all logical and physical cores.
