Hey I am a new member,but also a newbie and i would like to build a PC to do some light CFD simulations.
My CPU options would be the Ryzen 5 3600 and Ryzen 7 2700. Which one would be better? |

Out of these two choices: Ryzen 5 3600.
It is almost as fast as the Ryzen 2700 in compute-heavy multi core benchmarks. It is much faster single core. And most importantly for CFD: the memory controller is so much better, meaning you can choose whatever DIMMs you find for cheap, and still get decent memory frequency. |

If you plane to use the stock cooler, maybe it is better to buy a 3600X version accompanying better CPU cooler.

It usually doesn't matter too much. At least for calculations.
For pre- and post-processing, which you will be doing most of the time when learning the software, you still want a semi-capable graphics card. Used AMD RX 470 or 570 offer a pretty good value for money. 4GB of VRAM should be enough for an entry-level workstation. |
