PureOverclock has published a review of the PowerColor Devil 13 HD 7990 graphics card

AMD’s flagship 7970 graphics cards have been out for quite awhile, and have proven very successful with gamers. We’ve seen several variations from various manufacturers, and enthusiasts are always on the lookout for something unique, particularly when it comes to performance features.

We’ve also seen some graphics cards from PowerColor that fit this bill, to varying degrees. And it appears that PowerColor is taking things further than ever with the latest offering: the Devil 13 HD 7990. Sporting two GPUs on a single PCB, it’s an absolute behemoth in just about every regards. It has many enthusiast-oriented features such as a custom heatsink, low noise fans, voltage read points, improved power design, and a dual BIOS for turbo clock speeds, and this may just be the last great hurrah of the 7000 series Radeon cards.
