Q: Does CUDA support Double Precision Floating Point arithmetic?

 A: CUDA supports the C "double" data type.  However on G80
    (e.g. GeForce 8800) GPUs, these types will get demoted to 32-bit
    floats. NVIDIA GPUs supporting double precision in hardware will
    become available in late 2007.

Think I should wait to buy a NV8800 till the new hardware is available.

Simon:
The new hardware won't be an 8800 - rather, it'll be their next model, whatever they decide to name it. In the meantime they will release a die-shrink version of GF8800 that'll probably be called the 8900 series.

Same for Cell, by the way - the next hardware refresh will be able to do double precision in hardware much more quickly (first-gen Cell BE does, too, but comparatively slowly). Pity it will probably not be inside a low-cost system like the PS3 when it does get released.

Regards,
Simon.

did download the whole stuff of CUDA, read a lot and then tried to install the SDK 0.8.1 but it is not available without the hardware.... the SDK will install the CUDA Toolkit 08 automatic and it ask if hardware (8800) is installed.
Pitty to start programdevelopment without hardware is not possible.  :'(

Devaster:
you can use emulation mode ...

Vyper:
Correct there are a emulation mode to atleast see that the code WOULD work but you cannot count in speed in that euqation though ;-)...
