My MoBo's spec says that it supports SLI ready, but it doesnt say anything about Crossfire. How can u be sure that it supports Crossfire? and yes it has 6 pin connector, dunno what you mean by pci-e, but it supports pci 6 pin connector
I googled it , I was curious myself. A evga tech answers it at evga boards. https://www.evga.com/forums/tm.aspx?m=15540&mpage=1#15645 Correct, all EVGA X58 boards support Crossfire.
This applies to x58 and 1156 boards. Not older nvidia chipset boards.
Also crossfire support in some of these boards DOES NOT mean sli support.
But as I originally stated, Evga SLI x58 +1156 boards support ati crossfire in those same slots.
