Advice on technical requirements for the HP Z840 Workstation for numerical Simulation in OpenFOAM.

Hello friends.

Anyone of you could help me configure a workstation to make your purchase. I perform simulations with OpenFOAM with Ubuntu Linux operating system. The simulations are oriented flows in rivers.
What specifications should I look for?
To choose a suitable processor which reduces the computation time, is it necessary to have an Intel® Xeon® E5-2699 v3 (2.3 GHz, 45 MB cache, 18 cores, Intel vPro processor or lowest? Processor type graphics card should I use ?. How much storage memory should have ?.
Something else that should be considered?
Please any information please write.

The number of elements are more than 4 million cells and flow that simulates a free surface flow. Mass transfer and transport of sediments near the spur or groynes was observed. It is a scale model of a meandering river. An LES model or DES was made.

Best Regards
