So I originally had a 7870 installed, and i wanted to get a second one. The software and everything had been installed with the first one. So i got the second one, do i have to uninstall the software and re-install it, or not? If so, how?

Most suggest to uninstall the drivers install the card and re install the drivers. Personally I have never had to do that with any card I have Crossfired or SLI'ed I have just installed the card connected the Crossfire/SLI Bridge plugged the power connectors into the card and boot Windows up and Crossfire/SLI has been detected and went from there. But to be safe you should do as suggested I just personally have never ever had to do it.

But they're the exact same graphics cards. Before and after. I bilt the rig myself with a sapphire 7870, and then later decided to add another sapphire 7870.
