| 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. | |||||||||||
