XFX 9800 GX2 Graphics Card
Moving on to the GX2 there is not much we can say about the performance other than it is awesome. Throughout most of the review the card was able to outperform the 8800 Ultra and 3870 X2 and in some cases by a huge margin. In tests where there is not yet a dual GPU profile the card does lose out to the 8800 but these scenarios are few and far between but even when they do occur the GX2 always outperforms the X2.
