Sapphire 7790 Dual-X @ PureOverclock

The Sapphire 7790 Dual-X comes with a custom cooler cooler and a factory overclock that reaches over 1GHz. What’s particularly enticing is this Sapphire card also qualifies for the popular AMD promotional offer that tosses in an A+ gaming title in Bioshock Infinite worth $60 into the package. That sounds like an excellent deal, even if the performance isn’t terribly groundshaking as a more budget-oriented card. Let’s take a closer look at the Sapphire 7790 Dual-X and see how it fares.
