I have Sapphire VaporX 5770 and i want to upgrade (flash) the bios, i found VER012.019.000.002.036154 to be the last version, it is worth to upgrade? I DON'T HAVE ANY PROBLEM WITH my card, but i want to find out if i get something additional ("features") with this upgrade. If yes, tools like RBE Bios Editor and winflash are good? Or flash up from dos?
