Hi,
CPU-wise, I think the 6700k, 6800k or 6850K would be better options.
If you plan to have a second GPU, the 6700k and 6800k will not be
ideal (too few PCI-E lanes to run both GPUs at full speed unless you
get a special mobo). While the 2620v4 has 8 cores, it also has a low
TDP, so it's
80k atom MEM Benchmark System - 2fs time step - gmx2016.B2
GTX1070 - i7 6700k 4.00 GHz - 4 core - 42 ns/day - net cost per node (pc
chassis) ~ 950 EUR
GTX1070 - Xeon E5 2630v4 2.20 - 10 core - 58 ns/day - net cost per node
(19" rack) ~ 1600 EUR
GTX1080 will give you about the same performance
Hi Guille,
I'm not an expert on this, but it'll also depend on what kind of MD
simulations you want to run. Coarse-grained forcefields, for example,
don't benefit much from a GPU.
So what kind of simulations do you have in mind? Atomistic? QM/MM? How
many particles? ...?

Hi Guillem,
I can answer your last question - the 10xx series does indeed work well
with GROMACS (currently running GROMACS 2016 with a GTX1070), although I
would be inclined to get the GTX1070 if your budget can stretch to it.

Dear colleagues,
I want to buy a computer to perform molecular dynamics by GROMACS, and I have
several questions.
First of all, I am having doubts between the Intel Xeon E5-2620v4 (8 cores,
2.1-3.0 GHz) and the i7-5820K (6 cores, 3.3-3.6 GHz). The reason of my doubts
is the significantly
