Gigabyte is expanding its Super Overclock family of graphics cards with a highly tweaked model based on the ATI Radeon HD 5870. The Gigabyte GV-R587SO-1GD features a complete design overhaul over AMD's reference design, with the card sporting a typical Gigabyte-blue colored PCB, and a custom-design double-slot VGA cooler. The PCB uses Gigabyte's Ultra Durable VGA construction which makes use of a PCB with 2 oz copper layer, ferrite core chokes, low RDS (on) MOSFETs, and Japanese solid-state capacitors. The VGA cooler consists of a GPU base from which four copper heat pipes convey heat to aluminum fin blocks cooled by two 90 mm fans.

The GV-R587SO-1GD comes with out of the box clock speeds of 1000 MHz (core), and 1300 MHz / 5.20 GHz effective (memory), against reference AMD clock speeds of 850 MHz (core) and 1200 MHz / 4.80 GHz (memory). ATI Eyefinity support is retained with a display connectivity that resembles the reference design: two DVI-D, and one each of DisplayPort and HDMI. The GPU features DirectX 11 compliance, 1600 stream processors, and a 256-bit wide GDDR5 memory interface. It connects to 1 GB of memory.
