I have built a few computers before but, i'm behind in my knowlege of pci express
I'm currently useing a dual sli set up, but on a new computer i wish to make, i wanted to keep a old pcie card and use a set of new ones for my primary display. The old one whould not be sli because its not compatable with the cards i want to get. I'm wondering because i would like to reuse my older parts and not let them collect dust. I take advantage of haveing several monitors for diffrent things at the same time.
It not a actual problem i am just looking into options.
I'm basicaly wondering if you can treat pci express slots like pci slots for expansion, and i cant seem to find much info on it.
