Gigabyte quietly slipped in a revision of its Radeon HD 7770 OC graphics card (model: GV-R777OC-1GD Rev 2). The revision, while otherwise identical to the original, features lower factory overclock speeds. While the original features 1100 MHz core with 1250 MHz (5.00 GHz GDDR5-effective) memory, the revision ships with 1050 MHz core, and 1125 MHz (4.50 GHz GDDR5-effective) memory. Based on a custom-design Ultra Durable 2 PCB, with a custom-design cooling solution that uses a quiet 100 mm fan, Gigabyte's Radeon HD 7770 OC retails for US $129.99.
