Sapphire 7970 Vapor-X @ PureOverclock
 

The Sapphire 7970 Vapor-X comes with a custom cooler, and if history is any indication, we expect very big things from this Vapor-X technology, as Sapphire typically produces some of the coolest-running Radeon cards out there. Perhaps more importantly, however, the 7970 Vapor-X sports a factory overclock, to the tune of a 1GHz clock speed. This should provide enough of a speed boost for it to better competes against the competition’s offerings. Can the Sapphire 7970 Vapor-X live up to the expectations? Let’s find out.
