nvidea .... on a AMD based board .. yeah its supposed to be SLI ready but I'll hold out buying NVIDA products until they are tested, tried and trued. Even then I've been whooping butt with my archaic ATI's against all the new stuff ATI and NVIDEA both. I think I'll stay faithfull to ATI for quite a while.. In any event Make sure you have ALL of the Power Connectors attached !! this is a common screw up. Happens to the best of us.
