We checked in on graphics card specialists PowerColor at Computex 2012 and we were greeted with a pretty special graphics card. Based on the yet to be released dual-GPU Radeon HD 7990 (or possibly 7970 X2), this is the PowerColor Devil 13 HD7990. The Radeon HD 7990 is AMD's response to NVIDIA's GeForce GTX 690 - both are dual-GPU cards.
We don’t have hard figures on the specifications yet, but this is clearly one insane card. For starters, it packs a super massive triple fan cooler that has an equally elaborate and humongous heatsink. Because of the cooler, the card weighs a ton and will require a special device to offer it an additional support, else it might very well just tear the PCIe slot apart. Also, it relies on three 8-pin PCIe power connectors for power.
AMD is widely expected to officially announce the Radeon HD 7990 in the next few days at Computex 2012.
