Hi Szilard,
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.

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 GPUs. 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? -- Szil?rd
