ExtendedDoublesShaderInstructions on which cards?

I need the double-precision division operation inside a DirectCompute shader and apparently it is only supported if ExtendedDoublesShaderInstructions is supported. So I was wondering, which Nviida cards support this instruction? Very specifically, will Fermi cards such as GTX 480 and Tesla C2050 support this?

Secondly, I think this will only be available under Windows 8 and not 7?
