Hi everyone. This is my first post here. Just bought my son (and me) his first somewhat serious dedicated graphic card to play Diablo. The card I got is a XFX Radeon HD-685X-ZDFC (1GB). I was reading that this could be upgraded to a HD6870 by flashing with the appropriate BIOS. I was able to find the BIOS archive and realized there are many different XFX HD6870 BIOS. I'm now puzzled. Please advise me which is the most appropriate BIOS to use for my card. Thank you.
