I have an P35 DS4 REV.1.0 with the F3 BIOS. My system also includes 4 SATA HDDs (2 of them are in RAID) and has 2x1GB GKX Crusial RAM units and a 6300 cpu at 3GHz. The bus ratio is 1:1. My video adapter is an EVGA 7950GX2. Is it possible for me to upgrade to the F6 BIOS for better performanse or F3 BIOS is better???????????????????????? PLZ ANYONE
