Club 3D CGAX-7977S13 Pro Reviews

Club 3D launched two cards in its HD 7970 ‘13Series and if you’re after the faster one, the XT2 is your choice. The XT2 sports AMD’s GHz Edition Tahiti chip clocked at 1000MHz, but the card is factory overclocked to 1050MHz and the Boost clock is 1100MHz out of the box. Both cards, as well as the cards from Club 3D’s PokerSeries are special for their dual-fan CoolStream coolers, which performed well in our tests. Club 3D produced an ace from its sleeve when it decided to strap the HD 7970 with special cooling, especially in the case of its overclocked HD 7970 royalAce/royalKing and XT2 ‘13Series cards. The cooler is much quieter than the reference cooler used on AMD HD 7970 GHz Edition cards. AMD’s HD 7970 GHz Edition were originally designed to counter Nvidia’s GTX 680 cards, which were superseded by the GTX 770. The newer GTX 770 offers better performance per watt and its reference cooler is much quieter than AMD’s reference solution. Luckily the ’13Series features a CoolStream cooler and thanks to the 50MHz overclock it beats the GTX 770 in most games.
