Conclusion
We are disappointed with this model, which really brings very little in comparison to the previous generation. Our final score is based heavily on gaming performance tests, but the additional 10% you get in gaming power is no recompense for the higher noise output and power consumption.
This graphics card delivers a high level of performance while limiting power consumption. It's therefore clearly possible to increase performance from one generation to the next without upping power use too much.
