sorry if this is a really nooby question but im quite new to all of this so i wondering if it will.
My motherboard is a Gigabyte GA-797P-D3.
Thx in advanced
it will if the motherboard supports crossfire. look in your manual or google it, i cant find anything for Gigabyte GA-797P-D3. did you mean GIGABYTE GA-970A-D3? if so then no, it will not support crossfire or sli.
