Using both of my PCI-E slots at once

[dick_dickson]

I have an extra PCIE slot on my motherboard that I'm not using. I'm planning on buying a second video card for it, but how exactly do I go about mining with both cards at once?

I've heard about crossfire, but I've also heard that you end up with a speed that is less than the sum of its parts with crossfire. Is there a way for me to get both cards to work as two separate entities on my machine?

Just throw a second card in (and load drivers) then fire up your mining software.  Crossfire not needed.  Cards will work independently for mining.  Hopefully the slots are spaced a good distance apart or you may have cooling issues or need a riser cable.

I recommend you use a powered riser on the second slot. That will give more room for cooling and take some power load off your m/b.
