Sapphire HD6790 CrossfireX Review

To overclock today we used Catalyst Control Center which while limited, allowed us to reach the maximum figures before calling in other tools such as TriXX.

The overclock we achieved was reasonably healthy showing a little headroom. The core maxed out at 900mhz, any higher and the system would hardlock. The memory limit was around 1165mhz, any higher than this and we noticed a little artifacting.

The overclocked figures increased performance in Unigine by around 2 fps, surpassing the reference clocked HD5850.
