Hi,

no, this is not true. You can use CUDA enabled cards for computations
even if this is the only card in the system. It should be clear, that
then some resources of your graphics card may be used by other
applications currently running. Another thing is that your CUDA program
may use too much memory or has too many bugs and crashes your system..
this is the point where a second card become handy. For now, leave it
like that and start playing with CUDA. The specification of your card
here

http://www.nvidia.com/object/product_geforce_8800_gt_us.html

shows that you have 112 CUDA Cores and 512 MB Ram, which is fine to see
the magic.

Cheers
Patrick
