and there is a particular thing I would like everyone to remember.. even in the games where the HD5870 does a little better in fps than the GTX480 don't forget that the GTX480 is calculating not only the game graphics but also PhysX simulations. (( which in this case yeah Modern Warfare 2 and Alien vs Predator haves a heavy usage of physX ))
and the main fermi feature which is currently not very implemented in current gen games. Cuda and the GTX 480 shocking 480 cuda cores in a single GPU card.
also nVidia announced that hopefully it will be just a matter of some months after the GTX 480 release to release fermi dual GPU cards.

about sound and temperature, well I already shown the dead silent and cool FTW series for the GTX 480 water cooled GPU

Just Cause 2 isn't DX11.
MW2 doesn't use physx, and neither does AVP
nice try though.
i don't know why you're so adamant on trying to defend it when basically everyone says it's lackluster.
