If nVidia jeopardize themselves by intentionally breaking their driver support..
we are at the fruit.

After almost 2 year's of driver release Physx & Cuda are still broken on QUAD SLI ( GTX295 ) system.
For the Tesla sake Nvidia are unable, unwilling or literally doesn't care to provide ONE set where: physx, power save mode and the general performance are in line with the advertised specification.

What I wrote isn't altogether true, Nvidia call to have "fixed" the cache thrashing which have afflicted any Physx accelerated title on the dual-gpu consumer line which was not fully recognized by CUDA when four GPUs was connected by introducing the change proposed by these poor christ's in the 257 release, anyhow, in the process they crippled the raw power for the GTX 295 just in time for the Fermi launch.
