PowerColor Devil 13 HD 7990 Graphics Card Review @ HardwareHeaven.com
 

Recently AMDs partners were given the ability to design and release their own 7990 products (or 7970 X2 if you like). This would see two 7900 series GPUs on one PCB and every design would be different, PCB layouts, power spec, outputs, coolers... the works. One of the first to market with a 7990 is PowerColor with their Devil 13 card. This is as Extreme as Radeons currently get and today we put it head to head with the GTX 690 to find out which is best in the latest games including Max Payne 3 and Battlefield 3 at resolutions up to 5760x1080... all with our i7 CPU running at 5GHz.
