Dear Moises, What do you think about following GPU? NVIDIA TESLA K10 Dual GPU B3M66A 688982-001 Do you think it would be okay to order it with the configuration I mentioned in my previous email ? or would you suggest another GPU of Tesla Family? I just need your confirmation before we make a big investment in our computation power.
