Sapphire Radeon HD 7770 Vapor-X GHz Edition
Since their launch we have been impressed by Sapphires various Vapor-X coolers. Particularly in the case of the 6900 series the Vapor-X was able to take a noisy reference card and turn it into a quiet, cool running product which was much more desirable. Until now though the Vapor-X branding hasn't appeared on any 7000 series products, even though Sapphire have been releasing overclocked and custom designed models for some time.
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.
