AMD is different than Nvidia of course, but last I recall the odd 560ti 448 core you could only SLI with another 448c. Again, AMD is different and you can Crossfire similiar families. At worst CrossfireX with itself. At best, both 78xx and 79xx series.
I just follow the Charts, its hopefully possible to xfire between the 7900 and 7800 series then with this card.
