[gmx-users] Gromacs GPU system question

[Mare Libero]

Hello,

I am assembling a GPU workstation to run MD simulations, and I was wondering if anyone has any recommendation regarding the GPU/CPU combination.

From what I can see, the GTX690 could be the best bang for my buck in terms of number of cores, memory, clock rate. But being a dual GPU card, I was wondering if  there is any latency issue that could make its performances less favorable with respect to a GTX Titan.

Also, which motherboard, CPU is recommendable for this system.

Thank you in advance for you help,

Al
