Do I need to do anything special to get a HD5970 running at full chat. Just got a HD5970 to run a 3 screen eyefinity setup. Got it installed and DXDiag only showed 1gb gfx memory(not the 2gb of the card. Thought it was because crossfire was not set up, so went to ATI site and followed the instructions around crossfire. It stated that crossfire set up was an option in the Graphics drop down menu on cayalyst control panel, but that option is not on when i look for it. Have just come from many years of nvidia cards(In sli), so this is relatively new to me. Am I doing anything wrong, or am I worrying about nothing. Thanks in advance.
