"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."
