XFX HD-679X-ZDFC Pro Reviews

The XFX HD Radeon 6790 had the best energy results of all the cards. The thermal scores were good as well but not at the head of the pack. The card operated very quietly throughout the whole test suite and overclocked decently to 980 MHz core and 1250 MHz memory fully stable. XFX ran the 6870 PCB with two 6-pin power connections to allow for higher overclocking although the 6790s themselves don't need dual connectors. Gaming showed that this card was at the bottom of our test group but it put out good performance for being mid-range. The size of the card is average and should easily fit into almost all systems. The outputs are standard fare from AMD now with two DVI ports, two miniDisplayPorts and a HDMI port. Although, one of the DVI ports was labeled VGA and thus has a lowered resolution capability. The only cons were that the base of the heat sink was a bit rough and the gaps between the heat pipes and the heat sink base were large.
