Thank you for the research on this question. I think the question at this point is whether the bios upgrade is advisable? Will the diparity of the bios versions affect performance in XFire? I have to comment as well that the installation of CCC has been anything but smooth and I think may be contributing to anomolies in my performance.
This is the explanation I received back from our Technical Support:
"The perfect situation assumes both cards in Crossfire or SLI to have exactly the same specs including bios. As bios holds some information about for example internal timings, then if user has 2 different bioses then driver picks up the slower one card as the base and slows down the faster one. This way some percentage gain maybe lost."So it definitely would be worth flashing the BIOS on the older card. I still haven't received an answer as to where it can be obtained from but I will post here when I have the information.
