Will I receive my password recovery prize if I use NVIDIA Tesla or AMD Firestream?
No, these cards are not appropriate for solving password recovery tasks. Price/performance ratio is poor.
Study the performance table containing data on different video cards: http://golubev.com/gpuest.htm
Taking into account the specification of top card RV870 one - http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units#FireStream_series - can say that its performance is similar to HD5870 that is not the best card for passwords recovery.
The same concerns Tesla - http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#Tesla
We recommend systems based on AMD HD 6990. But you should take into account that the system shall comprise a power unit of sufficient capacity and an excellent cooling system as our software applies a constant 100% loading of video cards.
