ok, I have this problem with my Sapphire 4870 1GB video card; it has a certain issue with PowerPlay feature( games crash all the time because of it). So, I asked Sapphire if they had a BIOS update for this card, so they sent me an update, but it turned out that it was the one I already had installed(ATI Winflash) , so problem is not solved ( it turns out it's a known issue with Sapphire, and they don't want to fix it.) so, I'm just wondering is it safe to flash my video card with a BIOS from a different brand name ? Like will I damage it ? or fry it ? or is it safe to do ?
