got an 9500 pro comin from ebay, plan to mod/oc the bejebus outa it, but researching is giving me mixed answers on if i have to flash the bios or not to oc the thing, do i have to flash to oc if using the omega drivers? any amaizing overclocks to report...i thought this would be a more fun and cheaper way to replace my gf2 than buying an mid level card like a 9600xt or 5700.... any insight would be appreseated.
