Hi all,


I am planning to buy a GPU card for acceleration of AMBER11. After a round of search, GTX580 was focused.


The scale of MD is usually 30,000-50,000 atoms size. So, here come two questions:


1. Which memory should the GPU card be in my case? 1.5 G or 3 G? Is 1.5 G enough or not?


2. How many "ns" could the MD run in one day with GTX 580 1.5 G version?


Thanks!
