I suspect the 7900X3D will be the best deal in terms of value for money between the 13900K, 7950X3D, and 7900X3D. The 7900X3D only clocks 100mhz lower than the 7950X3D. Everthying else is the same -apart from the cores, of course.
But, as we all know, MSFS basically only uses only one core anyways (I know I am exaggerating, but you know what I mean; 12 or 16 cores does not matter for MSFS).
So, I assume the 7900X3D will have roughly the same performance as a 13900K, but with much less power consumption and better 1% lows. Also, I will be able to upgrade once more on AM5 without having to upgrade my mobo again. I will upgrade to a 7900X3D with 5600Mhz CL28 DDR5. I rather spent the 100 bucks on low latency ram than on 4 more cores that won’t be utilised.
What do you guys think? you going X3D, if so wich one; or you opting for the 13900K?
