Thank you for your info. I am planning to buy a computer with the following configuration: Intel 5820K Corsair H100i Hydro Cooling Performance MSI X99 SLI Plus Fractal Design R4 Seasonic X 1050W I am wondering if it would be a good idea to go for 3x GTX 970 instead of 2x GTX 980 since the cost

The 6-core Intel CPUs have only 28 PCI-E lanes rather than 40 like the 5830K/5860X which means that with a second GPU you'll get x16/x8 and with three GPUs x8/x8/x8. Also note that for the current GROMACS implementation, pairing a 5820K with two 980s will likely give a rather imbalanced hardware s

I am planning to buy 2x GTX 970 for 5820K overclocked to 4.5 GHz. I have budget limitations and not able to afford workstations with 2x CPUs. Let me know if you are aware of any cheaper alternative. Also let me know if in future Gromacs could become more GPU intensive allowing more GPUs with
