Today we see the first Vapor-X 7000 series card in the shape of a Sapphire Radeon HD 7770 Vapor-X OC Edition. This enhanced version of the 7770 runs at significantly higher clock speeds than the reference model on both core and memory and combines this with a dual fan, vapour chamber cooler and we will be putting it head to head against the GTX 560 in a selection of real world gaming and multimedia tests.
