Crossfire Compatability, ATI Cards, and Many Monitors in Help & Newbies Posted November 12, 2011 · Report reply I am currently the proud owner of this video card (XFX HD-489A-ZDFC Radeon HD 4890). Since it's no longer active, I can't buy the exact same card to ensure that I could safely bridge the two together. However, this one (DIAMOND A4890PE51G Radeon HD 4890) is available.If I get this second card, could I have up to four monitors active at the same time? Can I bridge these two cards together? Is there anything else I should consider before getting this second video card?
