The revision 4 bios with the new raid drivers SUCK!!! We have been trouble shooting for about 3 days as to why my buddies soyo dragon setup has been running such low scores on 3dse! We could only manage a 9,000 range score with the version 4 drivers and the new raid 2.32 drivers. We went to the version 3 drivers and the 2.31 raid drivers and are back up in the high 12,000's!!! Just a caution
