AMD's mildly elusive dual-GPU Tahiti XT boards will be making its way to HIS, in the form of the Radeon HD 7970 X2. Taking care not to follow the 7990 moniker, HIS has made an enormous three slot card to rival the size of PowerColor's Devil 13 HD7990. The HIS Radeon HD 7970 X2's 1050 MHz GPUs are individually cooled by separate heatsinks on top of its two fans, with the 6GB GDDR5 memory clocked at 6000 MHz. The meaty card is powered by three 8-pin PCIe power connectors, with a Lucidlogix PCIe switch bridging the two GPUs together. You'll also find two DVI and four mini DisplayPort outputs on the HD 7970 X2. Regarding availability, HIS has yet to announce a release date nor pricing. With such impressive specs, can a brawny Radeon HD 7970 X2 match the might of NVIDIA's powerful GTX 690?
