GIGABYTE Unveils its Radeon HD 7700 Series

GIGABYTE kicked off its Radeon HD 7700 series with a trio of graphics cards, the Radeon HD 7770 GV-R777D5-1GD (AMD reference speeds), the Radeon HD 7770 GV-R777OC-1GD (factory overclocked speeds of 1100 MHz core, 4.50 GHz memory), and the Radeon HD 7750 GV-R775OC-1GI (factory overclocked speeds of 880 MHz core, 4.50 GHz memory). The company didn't release a reference-speed Radeon HD 7750. All three cards are based on non-reference board designs by Gigabyte, consisting of Ulra Durable VGA+ PCBs and optimized large-fan (translates to lower RPM, lower noise) fan-heatsinks.
