Sapphire Radeon HD 5570 1GB video card review
"While this card’s GPU might have more in common with the Radeon HD 5670, the PCB and board design itself bears a closer resemblance to the Radeon HD 5450, providing us with a low-profile card that will fit in the smallest of chassis. While the Radeon HD 5450 is treated to an entirely passive cooling solution, Sapphire’s Radeon HD 5570 comes equipped with a small, single slot active cooler with fan.
As you’d expect, this card requires no additional power, with the PCI Express 16x slot providing all of the juice required. The usual CrossFire inter-GPU connectors are also absent here, although two (or more) Radeon HD 5570 boards can still be run in a CrossFire configuration, with data sent over the PCI Express bus instead."
