Thank you very much for your input.
At the moment we want to buy a single card (GTX-580?) in order to gain experience in working with GPUs. In the future we will probably like to have a cluster, especially when multiple GPU cards will be supported by Gromacs.

Tesla cards won't give you much benefit when it comes to running the
current Gromacs. Additionally, I can tell you so much that this won't
change in the future either. The only advantage of the C20x0-s is ECC
and double precision - which is ATM anyway not supported in Gromacs on
Gromacs in general doesn't use much memory so unless you will want to
run gigantic systems with a single card, C2070 will not give you any
added benefit at all, in fact 1-1.5GB/card should be more than enough.
What kind of machine are you planning to buy/how many GPUs?
