From what I understand about the card if you are running 4 monitors its like two 4850 1gig cards but its running off 1 card. For more information I would check sapphires website. The card is more than enough power for world of warcraft. If you play fps games you can take full advantage of the card and crossfire. Do what makes you happy. It's working great for me. I switched to boxing 5 on 2pc. With the expansion my q6600 system couldnt handle running 5. My 4850x2 card runs two monitors on my i7 920 system. I capped the max fps at 50 and my game play has never looked better. You can buy the triple head go but to me its a waste of money. For me, the question is, why spend the money for additional hardware when all you have to do is plug in your monitor to the dvi? So far for me it works fine.
