Diamond's HD 4870 X2 XOC Edition has surfaced online for $574. The board shares the same core clock as its watercooled brother - 800 MHz, while the memory is clocked at 3900 MHz.

Diamond have proven themselves to be capable of dishing out some pretty mean pre-overclocked graphics cards, especially in the case of the Radeon HD 4870 X2 XOC³ H2O Edition which also came equipped with a Koolance waterblock.

Now another HD 4870 X2 XOC Edition is available, only this one sticking to traditional air cooling. The core clock speed remains the same as its water-cooled brother at 800MHz whilst the memory speed takes a slight drop from 4400MHz down to 3900MHz. The rest of the card appears to follow the usual 4870 X2 design.
