How we test

We've changed the system setup to better reflect the kind of setup that would house these mid-range cards. Out goes Intel's Core i7 965 and X58, replaced by Core i5 750 and P55.

We've also turned the settings down on the games and benchmarked them at 1,280x1,024, 1,680x1,050, and 1,920x1,080.

Temperature To emulate real-world usage scenarios, we record GPU core temperature both when idle and whilst playing Crysis Warhead. And, for a worst-case scenario, we throw in numbers from the FurMark stress test.
Power consumption To emulate real-world usage scenarios, we record mains power draw both when idle and whilst playing Crysis Warhead. And, for a worst-case scenario, we throw in numbers from the FurMark stress test.
Noise Albeit not scientific, we use the tried-and-trusted human ear to share an opinion on GPU noise.
