Re: Hardware vs software crossfiring??
when you're joining two pieces of hardware together, the best way to do it is with a hardware connection. In this case, an SLI/Crossfire bridge.
They will show up as two seperate cards in device manager, Xfire/SLI configuration will be within the Catalyst software center downloadable from AMD's website. I can't imagine how or why It would be referred to as a software crossfire, I didn't know that existed. I know you can do Hybrid crossfire (an expander card working alongside onboard graphics) but not 'software crossfire'.
EVGA SLI Micro Z68 // Intel i5-2500k // 8GB Corsair Vengeance 1866MHz // Overclocked 2GB MSI R9 270X // Corsair Carbide SPEC-03 // Kingston Hyper-X 120GB // 2TB WD Green + 500GB WD Black
