Dear all,

I'm about to build a (rather cheap) computer for personal use. I will mainly use OpenFOAM and another in-house built solver from a company based at my university. I have a budget of 1300 swiss francs (~1400 USD) for the whole thing.

I have some questions about the CPU, as I will use the computer for quite a lot of stuff including CFD, Machine Learning (in Python/MATLAB) and a bit for gaming.

I'm not tempted by GPU acceleration for the moment, so the GPU will be based on my gaming needs (I don't need a very powerful one, just one that works well, perhaps a GTX 1660 Ti or similar)

But I'm still confused about my CPU choice, and based on a first estimation, my budget for the CPU lays around 450~550 USD. Here are my first thoughts:

-AMD Ryzen 9 3900X (downside is 2 channel, not good for CFD scaling but good for the rest)
-A similar range Threadripper (opposite of the above)
-A similar range Intel Core

Thing is I read that the Ryzen 9 3900X performs quite well also for CFD even with 2 channels, and the new generation is coming in a month, so I was wondering if it's worth it.


Thank you !
