• Quadro5010M
• Quadro6000
• Tesla C2075 (Windows)/Maximus configuration

This means that the minimum your system should have is the above. If you can increase your processor's power to a Quad or an Octa core processor then that would be far more beneficial.

I would also suggest that you increase your RAM to32 Gigs if possible. This is because you will definitly need the processor speed and alocated ram.

Last I would suggest that you run your operating system on an SSD (solid state disk) so that the operating system is running at the highest possible performance. This will definitly affect how long your renders run.

I hope this information helps.

What's the most powerful configuration concerning quality / price ratio ?
