Only in specific cases though. I don't want you to think by my post that having a second card wouldn't be worth it when you're playing in the highest detail settings possible, because it would be by far. But if you're going to be playing at a more reasonable resolution and antialiasing/anistropic filtering settings, then one card, especially the X1900XTX, would be more than enough for you.KidBoy17 said:Smith is correct on this and the reason why I wouldn't go with a cross fire chipset is because I wouldn't need a second video card. I heard from a reliable source that having a second card can sometimes slow down your computer.
