I know this is an odd question, but I just upgraded from my xfx 7750 to a Gigabyte 7850 and was wodnering if I could/or would see any benefit in just putting it into my unused pci-e slot? I'm not really experienced with sli or xfire, I know its a noob question. I don't want to upgrade to another 7850 yet, maybe in 6 months or so. My current specs
FX-8350 oc'd 4.6ghz hyper evo 212
Gigabyte 970A mobo
Gigabyte 7850 2GB DDR5 oc'd to 1000mhz
8GB HyperX Blue 1600mhz
ThermalTake TR2 600w
I am not as familiar with AMD/ATI cards as I am with NVIDIA but I think that with AMD you will need to use to of the same model in crossfire to see any benefit. With my GTX 680 I use a GT 640 for PHYSX, but I don't know if an equivalent is available for the AMD video cards.
