Underneath the heatsink the improved design continues with plenty of components which are designed to minimise temperatures and maximise stability and reliability. That's before we consider the external switch for BIOS selection.
In terms of performance the Devil 13 scores well. With the performance BIOS enabled we get framerates which compete with the similarly priced GTX 570 OC and the card remains near silent the majority of the time. Temperatures are also decent considering the extreme core and memory speed and the card remained stable throughout our testing.
For value, again the Devil 13 impresses. The thorough bundle and overall build quality mix with the standard AMD 6970 features to create a well-rounded product which is backed by a decent warranty.
The PowerColor 6970 Devil 13 allowed us to game at 1920x1080 with maximum detail in all of the latest games, including Skyrim, Modern Warfare 3 and Battlefield 3. A hugely impressive version of the 6970 which impresses from the outset and never lets up.
