Ok so i own a evga 790i motherboard and it only supports sli and not crossfire. My problem is that when i go to the dell webpage or the alienware webpage all their system configurations that have a 790i mobo support crossfire and sli, how did they do this? Ive heard something about hacked drivers but i dont know anything about them..... Would it be a dell bios update or are they using a edited 790i chipset? Please some1 help i really wanna use crossfire on my mobo. Thank you
