I have a Gigabyte M57SLI-S4 AM2 NFORCE 570 mb and am currently running an Nvidia 256mb 8400gs (yeah, I know, not the best card, but what I could afford when I bought it). Anyway, a friend of mine also has an Nvidia 8400 gs that he is replacing with a better card and I was wondering what I would have to do to set them up on my system. Do you just plug in the other card and that's it? Which one do you connect the monitor to, or does it matter?
Also, I know both cards have to be the same, but does it matter if the manufacturer is different?
