Comparing different Lenovo Workstations
 

Hi,
Looking for advise on selecting a Lenovo workstation mid range (limited budget). Mainly model building, meshing.
some solving (primary to testing before shipping to HPC cluster)
and pre/post. Openfoam and Star-ccm

Current the choice seems to be between Lenovo P7 and PX:.
Configurations:

P7: Intel® Xeon® W7-3445 (or maybe Intel® Xeon® W7-3465X)

or

PX: 2 x Intel® Xeon® Gold 5416S-processor or
(maybe 2x Intel® Xeon® Gold 5420

any advice on memory configuration: 4 x 32 Gb, 6x 32Gb or 8 x 32 Gb

Thanks in advance.

Best
Roued
