I need help on two questions. Let's go. 1. On my Biostar TA890GHB I have integrated card HD4290. I see that integrated card supports Hybridcrossfire and I need a list of graphics cards that would support that. And 2. At sister computer is APU A4-4000. I'm also interested in the list of graphics cards who will do in dual graphic mode. I hope that you will quickly and with porcine information replies. Thanks in advance. .
