Hi all, I was wondering if someon could help, and maybe has a similar vcard i just bought this videocard: Sapphire 7970 3GB dual X model 11197-11-40G - it's not the OC version, just standard with dual x cooler but searching on the web just growth my doubts.... first of all, it's not specified neither in the sapphire website if the card has got the dual bios switch... even for the OC version. I hope so for flashing one with this version (because they seem exactly the same card!) as i see my PCB is the blue one: they say it's newer than the black one, wich is the reference... wich is better? and will the new pcb features Boost technology? Because there is an identical version called "SAPPHIRE HD 7970 3GB GDDR5 OC with Boost"
