Hi, 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 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? -- Szilárd On Thu, Aug 4, 2011 at 8:59 AM, Jagdish S.
