Autodesk CFD performance problem

Good day! We in our organisation use Autodesk CFD 19.2 during design process of Product(Electrostatic precipitators, bag filters). In most of cases its a huge models, so caculation takes a long time.

We look for some speed up: Cloud computing, buy server for calculations or some upgrade/update of PC to stronger one. A few weeks ago, we had the opportunity to use a new PDM server for few days to run CFD on it and make conclusion about its performance for calculation speed.

In attachment you can see comparison of PC and SERVER performences. Final time speed up is about 2 times, and for us it bad result(considering the multiple increase in server power over a personal computer and the cost as well). Our hope was 5+ times, to make calculation time of our big models less than 12 hour.

Can you please make recomendation:

Can specialized video card speed up calc process? If yes what the parameters should it have to operate with models which has grid 20-40 millions elements(40-100Gb RAM)?
(According Autodesk System requirements there is recommendation to use Nvidia Quadro 4000 etc.)

Thank You in advance for any support.
