Palit is one of the first AMD board partners to release a custom Radeon HD 4870 version. Their new HD 4870 Sonic Dual Edition comes with a completely revamped cooling assembly that features two fans to keep the card cool. Also included is a DisplayPort connector and a Turbo switch which lets you select the operating frequencies of the card. The mandatory "overclocked out of the box" is included as well.
